Don't be a plank - Are plank exercises the be all end all?

One of the most common core exercises you see people doing, most often encouraged by PT's, is the plank, also commonly called the bridge. It is a challenging isometric exercise and a true battle of will and determination as you fight the burn and try to hold it for as long as possible. Yet, do you really need to be doing this exercise? Is it really that effective? Honestly? Once you can easily hit the 60 second mark, it isn't. Now don't get me wrong, your bog standard plank has a place but only for beginners. Why you may ask? Well let's see...

Table of contents


The only real measuring stick of a plank is how long you can hold it for. Whether it's 60 seconds or 5 minutes, what exactly are you training? Endurance more than anything else. The longer you hold it may add up to impressive numbers and a sense of achievement however holding planks for a long time is more of a waste of time than anything else. The reason why is because there are far more efficient and effective ismometric core exercises that take only a fraction of time to do but provide many more benefits.

Sure you could have someone add a weight plate on to your back to add more resistance to elicit more strength, however it quickly becomes an endurance exercise again and you can only add so much before it becomes unsafe to do so. Indeed, if you suffer lower back issues then adding weight can exacerbate them. Others may focus on moving an object from one side to the other in front of them creating a small degree of instability, however again it quickly becomes endurance.

At the end of the day whilst the plank is challenging for most at the start, once you can do multiple sets of 60 seconds no sweat then it is no longer challenging. Rather you should move onto something more productive.

Carry over

The plank when done correctly strenghtens your inner core muscles, allowing you to create a stiff, rigid spinal position. There is no doubt about that. The problem is that this is only in one static position with only gravity working against you. This is a position that we as dynamically moving creatures rarely do or find ourselves in, unless of course you are doing planks. We move in various planes of motion and axis and face resistance from different directions, thus the standard plank offers little carry-over.

Problems it can cause

The plank is often cited as effective and easy to do, suitable for all kinds of people. In reality it is not,

One common issue with planks especially when done with poor form is lower back pain. Holding planks for extensive periods of time eventually ends in form degradation, which can contribute again to lower back pain. The plank also works the muscles at the front of your body whether it is the shoulders, chest, abs or quads. Over time this, with the propensity for people to work out their "mirror muscles" more than their posterior chain coupled with our typical long sitting habits only reinforce poor posture and lower back pain. If you're looking to help your posture through planks then back bridges/reverse planks are what you should be doing.

Another issue is that the plank is as already mentioned an isometric exercise. Isometric exercises are proven to increase blood pressure. If you suffer from hypertension or pre-hypertension then you should avoid them, or at the very least hold them for less than 60 seconds.

Plank variations

There are a whole load of alternatives to the standard plank that make it more challenging, providing a more effective and efficient workout. Firstly, below is a list of some of the other forms of the plank that can be done. You will notice that each involves a greater degree of instability than the standard plank. This means your core has to work harder to maintain your position.

  • Side-planks: Creates a greater element of instability, especially if only using your hand rather than forearm as the contact point. Can be easily made harder by raising your arm up or/and top-side leg upwards. Can be made easier by having your knees on the floor. (YouTube clip)
  • Yoga side-plank variations: This video from Yoga With Adrienne shows other side-plank variations that add an extra challenge.
  • Bird-dog: A yoga/Pilates exercise, this involves raising one leg off the ground whilst raising the opposite arm until both are parallel with the floor. Can be done on knees for beginners or on your foot to make it harder. Hands can be made wider to make it easier or narrower or even overlapping to increase difficulty. (YouTube clip)
  • Swiss ball/wobble board/Bosu ball planks: Placing your hands or your feet on a Swiss ball, wobble board or Bosu ball creates a far greater degree of instability requiring greater core control. Can be easily scaled for difficulty as well. (YouTube clips of Swiss ball plank and Bosu ball plank)

The first three can also be done like the fourth one once you build up the balance and core stability for it. If you performed these exercises with the same degree of instability then you'd eventually end up with the same issues as the standard plank. The beauty is however that you can easily adjust the instability of them to continue progressing them.

Other static isometrics

Other isometric exercises that can be done instead for greater effect:

  • Hollow hold: Also known as the banana, this involves a greater contraction than a plank and with arms above head off the ground and legs up makes it far harder than a plank. (YouTube clip)
  • Boat pose: A yoga pose where your butt is the only contact point with the ground as you keep your torso and legs rigid in a V-shape with your arms out in front of you. (YouTube clip)
  • Hanging hollow hold: As the name suggests, this is the same as a hollow hold but you are performing a dead-hang from a bar. (YouTube clip)

These three exercises all suffer the same problem as the standard plank in that after a while they become less challenging and more endurance focused as you get better at them. Though you'll definitely be feeling and seeing the difference compared to standard planks if you are doing multiple sets of 60 seconds of these ones.

Isometrics with additional dynamics

So far all the exercises we have looked at involve gravity as the resistance. We can however add a whole new dimension to core isometric exercises by adding additional frontal and transverse plane dynamics for greater development:

  • Arms out resistance band side step: Also known as the Oak Tree Step Out, this exercise works you in the transverse plane. The side step creates tension in the resistance band, which requires you to tighten your core to prevent it twisting you round. (YouTube clip) Can be made harder by taking a greater step or using a heavier band. You can also use a cable-pulley machine allowing you to make the weight heavier as needed. (YouTube clip)
  • Suitcase carry: Basically a 1-handed Farmer's Wark, you hold a weight in one hand by your side, rather than one in each hand. This exercise works you in the frontal plane. You contract your opposite side to prevent the weight pulling you to the other. Perform with a walk to create more instability due to hip movement tugging at your core muscles. (YouTube clip)
  • Dynamic bird-dog: The same as the bird-dog listed above, however instead of keeping your leg and arm parallel to the floor you bring one or both in and out for a specific number of repetitions. (YouTube clip)
  • Dynamic side-planks: This video shows twenty variations of the side-plank, most of which involve movement to add greater dynamics to the exercise.
  • Resistance band dynamic bird-dog: Same as above however with a resistance band. The pull of the band makes the bird-dog more unstable meaning greater core control is required to maintain it.(YouTube clip)
  • Dumbbell tight step-overs: A hard one to remember what the name is, however this essentially where you hold two dumbbells at shoulder height and perform tight side-steps where you alternatively move your foot above or behind your other foot. With the added weight you can feel each little movement your hip movement causes to your core and the tightening required. Obviously adding heavier weight increases the difficulty.
  • Chest/back/shoulders/biceps exercises: Yep, these exercises all work your core isometrically when you brace your core properly or focus on making it stiffer. As you progress to heavier weights, you core also needs to adapt to the increased load. Standing versions should be done rather than seated ones to help focus your mind on bracing your core.

Sum up

Hopefully the above has given you some fresh insight and ideas on how to move on from bog standard planks to better and more effective exercises that are also more challenging. Your lumber and thoracic spine will also be happier for not having to go through tediously long holds in which form inevitably degrades. The above alternatives are only the tip of the iceberg and there are many other exercises that can work your core isometrically in a way that provides real world benefit. If you have any questions then feel free to ask away in the comments or send me some feedback!

DIY Cannonball Grips - How To Make Your Own

Something I always wanted to do was make my own set of cannonball grips to take my pull up and grip training to the next level. One of my local leisure centres had a gym rig that had molded on cannonball grips but obviously these aren't portable.

Looking online for some pre-made cannonball grips and well they aren't cheap especially for something so simple. So eventually I decided to dive in and make my own. This post will share with you how I went about doing it, the costs, and some of the setbacks and remedies I came across.

Table of contents


Several years ago I saw a video on how to make cannonball grips however I can't remember where at. Luckily the basics of it remained lodged in my memory so I knew what I needed to go for. The equipment needed is incredibly simple and easily attainable:

  • Two baseballs or other kind of hard ball to use as the cannonballs. Whatever you choose ensure they are solid hard balls. See Problems encountered below for why.
  • Two eyebolts at least 4-5 inches long with a good thickness. For mine I choose ones that were 9mm thick.
  • Four nuts and four washers. Two pairs for each eyebolt. This helps keep the ball in place.
  • Two straps for attaching the grips to a pull up station.
  • Two carabiners to attach the eyebolts to the straps.
All the bits needed to make a large and small pair of cannonball grips.

Along with this you only need a few basic items to assemble the grips:

  • Adjustable wrench
  • Drill with a Spade or Spur Point wood drill bit a size down from the bolt. I.e. 8mm for a 9mm bolt.
  • Clamp for holding the ball in place whilst you drill.

(Back to top)

Sourcing the parts

Firstly I went onto Amazon and purchased two Wilson baseballs at £4.49 each. I would strongly recommend not buying these ones. Again see Problems encountered for why.

I also bought a two pack of 6cm diameter Efco wooden balls for £2.70. I bought these so I could try different sized grips to vary my exercises.

Next I ordered a set of Joyhoop Hammock Straps, which came with carabiners for £11.98 (at the time). There are other straps available and for cheaper however I liked the look of these ones and they were also shorter meaning the grips wouldn't end up hanging too low. After receiving them I can currently testify that they are indeed a good job able to support my 79kg body, and the carabiners are good and thick.

I went to the nearest hardware store to look for the eyebolts, however the smallest length they had was 6 inch, which I felt was too long. After driving around a few places I decided to return and just buy them. They cost 90p each slightly more than other places but unlike other places each bolt came with two nuts and two washers attached rather than one. This meant less hassle to find the right sized nut and washer.

I bought five eyebolts, one of which was to be a spare. I intended to glue the balls and nuts into place so needed one eyebolt for each grip. You could if you want use just two eyebolts and swap the grips for a different size for variation however for the cost of the eyebolts why waste the time it'd involve?

As a bit of a DIY enthusiast I already had the equipment needed to assemble the grips so I didn't need to deal with that stuff. So in total (excluding the Efco wooden balls as they are an extra) this cost £22.76. Not too bad, though turns out I could have done it for £19.76. Indeed even less with a cheaper set of straps.

Making the grips

When it came to making the grips, the process was easier and quicker than sourcing the parts.

Firstly place the ball into a vice clamp. The one I used had a moveable neck allowing me to have it positioned so that I could drill straight down without hitting anything.

The next bit is the hardest bit: trying to drill through the ball so that it goes straight through the north and south poles of the ball. Unless you are using a drill press, which takes the problem away, you will have to depend on human judgement and you will not get it perfect, but you should be able to get it close enough. The drill bit should go through easy enough though there will be some cork dust ejected so do it outdoors or somewhere easy to hoover it up.

Vice, vice, baby! Make sure its tight enough to stop the ball moving whilst drilling.

Once the hole has been drilled through get an eye-bolt (with a nut and washer already on it) and start to screw it through the ball, or vis versa. I found screwing the ball the easiest way of doing it. Keep screwing until you have enough of the bolt protruded through the other side of the ball so that you can place on the other washer and nut. I found the hole a good width and snug fit for the bolt allowing for a tight fit.

After this tighten both nuts with the wrench. For added stiffness to prevent the nuts from possibly unscrewing over time you can apply glue to the bolt at either end of the ball and screw the nuts tight on top of it and then letting it cure.

Give both ends a good tighten with the wrench.

The final thing to do was to simply attach the eye part of the eye-bolt to the carabiner, which itself was attached to the eyes of the strap, and voila! A cannonball grip.

Problems encountered - 1

Everything seemed to go great. I had done the baseball grips first and thought they looked great. I had orignally screwed the balls to the top of the eyebolts and intended to get the bottom of the bolt grinded off. However after hanging them there was no need for them to be screwed so high considering the height of my pull up bar. A bigger problem with them however was that they felt like if I hung my entire bodyweight off them then the baseballs would tear through the nuts at the bottom.

Checking online it turns out proper baseballs are made out of a combination of cork, rubber and wound string inside a leather skin. Some are simply pure cork. The ones I had purchased whilst feeling quite firm on the outside consisted of nothing but sponge. They bounced well but that was it. At least I can fun with my daughter throwing them about.

Looking around online for a pair of proper baseballs I couldn't find a good cheap ball or trust they had a good amount of cork in them. You could get full cork bodied ones yet I found them hard to find. I also wouldn't be able to tell if they were truly solid until delievered. They all seemed to be over £6-7 each. For something that goes for a couple of bucks in the states, it appears not for the UK. Had I not already wasted £10 on those soft baseballs I may have went for two of these other ones.

A day later I had to go Sports Direct to get my daughter a new pair of trainers and thought I'd chance my arm in seeing if they had any baseballs. I didn't hold much hope but lo and behold they did, and thankfully these Slazenger ones had a solid cork core and for only £2.99 each discounted from £5.99! I would caution that they do also sell a soft ball version, which should be avoided.

Arriving back home I went straight away to drill holes in the two balls and found it a better process than for the sponge core ones. When it came to putting the eyebolts through them it took a good steady screwing action to do so and it was a nice tight fit. After tightening the nuts I gave them a test and bingo they fitted the bill perfectly.

(Back to top)

Problems encountered - 2

Another issue I had was with the Efco wooden balls. It turns out it was next to impossible to screw the 9mm eyebolt through 8mm holes. I tried to find a 9mm flat-wood/spade wood drill bit (external link) of any kind in my local hardware shops however couldn't find anything but even numbered sizes over 12mm. So I had to use my 10mm Spur Point wood drill bit (external link) instead. It didn't matter in the end as tightening the bolts enough ensured the ball didn't twirl around.

Unfortunately the 10mm Spur Point drill bit wouldn't drill through the "pilot" 8mm hole without getting stuck so I decided to drill a new hole through it (intersecting the original hole track). Maybe a Spade wood drill bit wouldn't have had this sticking problem?

Filling in the gaps with some good ol' wood filler.

The gaps and damage to the ball from the original hole I filled in with wood filler. Unfortunately it was white coloured whereas the balls are a natural wooden colour, however I may end up painting the balls anyways. They are untreated wood so would benefit from a coat of something if I use them in poor weather.

After it sets give it a nice sand.

Thankfully the second ball hadn't been drilled through yet so I didn't have the same problems.

Triceps Dips

The full triceps dip is an advanced exercise that when performed correctly is one of the best exercises for the triceps muscle especially in calisthenics. It also hits the front of the shoulders and chest muscles making a great compound movement.

Unlike triceps bench dips, which require your feet to be supported, unaided dips utilise the full effect of gravity on your body to create the resistance, which can be increased with weight added such as with a dipping belt or weighted vest.

Back Bridge

The bridge, also known as the back bridge, is a simple and basic but effective lower back strengthening exercise that can be done anywhere.

The bridge also targets your inner core and gluteal region, helping improve your posture and your posterior chain.

Training wIth injuries - Long head of biceps

The following is my personal experience in how to adapt to a difficult injury to recover from, that of the long head of the biceps.

Triceps Bench Dips

The triceps bench dip, also simply known as the bench dip, is a great beginners exercise for targeting the triceps in a calisthenics manner. It also hits the front of the shoulders when pressing back up as well as targeting the upper back musculature as you press yourself up at the very top of the movement.

This exercise can also be performed anywhere you can find a ledge such as a chair, window sill, bench or similar.

Dorsal Raises

The dorsal raise, also known as the prone back extension, is a simple and basic but highly effective lower back strengthening exercise that can be done anywhere.

The dorsal raise also targets your inner core and gluteal region, helping improve your posture and your posterior chain.

The king of upper body exercises, the pull-up is for the upper body what the squat is for the lower body. Utilising almost every muscle in the upper body to execute and stabilise, there is no better exercise for developing a great upper and mid back whilst doing so in a holistic way. Mastery over your own body with the pull-ups outstrips anything you can achieve with barbell rows and lat pull-downs.

Seated Forward Bend stretch

The Seated Forward Bend is a stretch that stretches the posterior chain muscles from head to toe. It is also a yoga pose where it is called paschimottanasana (POS-chee-moh-tan-AHS-anna), meaning "west stretching", where west refers to your back. This is due to your back facing west during morning worship, which is done facing towards the rising sun in the east.

Calf Raises

The calf raise. A staple of those who seek to enlarge the back of their lower legs. It is also probably one of the simplest and easiest exercises than can be performed, however has variations that can make it incredibly hard.

This exercise is rarely at the forefront of most people's routines, with quite a few not doing them at all. Indeed calf raises are not the only way to target your calves. Any balance, stability and plyometric training targets them good and more functionally. Squats and deadlifts both recruit the calves in their movements.

Pull-ups - My journey to the perfect rep

Pull-ups, also spelt as pullups or pull ups, are one of the hardest and most sought after exercises for people to achieve. That ability to be able to pull your entire bodyweight up towards the bar against gravity is something that cannot be replicated by any machine or free-weight. It's amazing to see people who can shift literally tons of weight on a bar but absolutely fail to lift their body off the ground on a bar.

Tuesday 28 August 2018


Push-ups, also known as press-ups, are a staple of bodyweight training. Primarily targeting your pectoral muscles, when done properly it is a highly effective full body workout that also hits the back of your arms, core, and legs. It also has the added benefit of being able to be done anywhere without any equipment and is the safest chest exercise you can perform by yourself.

Often performed with poor form, quite a few weightlifters who are able to bench press very heavy loads struggle to be able to do a set of push-ups.

Parkour Examples and Caution

Following on from my post What is Parkour?, which explains what Parkour is, how it differs from Freerunning and what its origins are, we focus on examples of the fundamental element of efficient movement, Parkour moves, and cautions when practicing.

What is Parkour

A pastime that I always wanted to get into and eventually did was the art of Parkour. We have all seen at least one instance of someone wall jumping and doing crazy acrobatic moves, and who can fail to be inspired by the Parkour themed video for David Guetta vs The Egg's "Love Don't Let Me Go"? Or by Parkour legend S├ębastian Foucan's Parkour chase in Casino Royale.

So good I just had to embed it!

Bodyweight or calisthenics?

A common misunderstanding in the fitness world is the terms bodyweight and calisthenics. Some personal trainer's even advertise themselves as specialising in both. If you come across such a trainer I'd suggest finding another one who knows what they are talking about and has experience of the terms they use so carelessly.
