Isometric exercises are often looked at as fluff work to be left for the end of a weight-training workout. Holding a plank for 30 seconds is the ‘go-home’ move for many a gym goer. The science would suggest that you’re likely missing a trick if you’re not giving isometric exercises the respect that they deserve.

We take a look at the how and why, then hook you up with an isometric workout that you can do absolutely anywhere (with a sneaky device that will let you essentially hack your workout for maximum effectiveness.)


What are isometric exercises?

They are a way to strength train using a static contraction. Your typical way of strength training would take your joints through a complete range of motion. For example, a bicep curl would mean repeatedly shortening the angle of your elbow joint against resistance to achieve a contraction and, eventually fatigue the muscle.

Isometric movements keep the joint fixed while you flex and contract the muscle against resistance for a set period of time rather than for a number of reps. The plank and the wall squat are two examples, but we’ll hit you with some more workouts later.


Isometric exercise benefits

No need to take my word for it that isometric workouts are beneficial. Let’s look at some cold, hard evidence to see if we can get you from a half-minute squeeze to actually structuring your routine around isometric moves.

  • Effective: a paper in the Journal of Sports Science found that isometric exercises matched dynamic weightlifting exercises for strength gained over a 9 week period. As an added bonus, the isometric group’s muscles were stronger in isometric contractions than the group that performed dynamic exercises. Other studies showed that isometrics are effective for both weight loss and muscle building too.
  • Convenience: isometric routines can literally be done anywhere. Sitting at your office desk, on the couch watching TV, while you wait for your dinner to cook – wherever you can think to do them, they can be done.
  • Time: if you’re short on time, isometric routines are fantastic. They don’t take anywhere near as long as a weight training routine at the gym.
  • Injury: a muscular injury may cause you pain when contracting through a full range of motion. If you can find an angle that allows you to contract the muscle without pain or making the injury worse, you’re on to a winner. Isometric exercises allow for this


Isometric exercise device

Before getting to the Isometric workout, the best part about isometric exercises is that all you literally need is your body and something to push or pull against to offer resistance. Oftentimes your body can be what provides that resistance too. Having said that, there is one tiny piece of isometric workout equipment that can change the game for your routines.

One of the issues associated with isometric workouts is that they’re quite hard to measure. You can’t see how well your muscle is contracting, how much resistance you’re applying and, overall, how effective your workout is. It’s guesswork – and that makes progress difficult…until now.

The Activ5 is a tiny smart device that doubles up as your isometric exercise coach. It can measure up to 200lbs of force applied to it and is practically a gym in your pocket.

The device syncs with your smartphone to provide you with over 100 workouts for every scenario, contains training games and also acts as your coach, showing you how much pressure your muscles are applying and whether you need to increase or ease off. Who needs a PT?

With outlandish claims almost synonymous with new fitness products, it’s a pleasant surprise to see scientific studies that back the effectiveness of this portable piece of isometric workout equipment for strength, muscle and fat loss.

It’s recommended you pick an Activ5 up – it’s the isometric exercise device to have and will really take your isometric routines workouts to the next level.


Isometric workout that you can do absolutely anywhere

As promised, here is a 5-10 minute isometric workout that you can do anywhere and get great muscle building, fat loss and strength results. The pictures show the exercises performed with an Activ5, but they can be performed without. You’ll just know exactly how much pressure to apply for best results when performing each of the isometric exercises if you do use an Activ5.

Start with holding each exercise for 30 seconds to a minute for two sets. As you progress you can increase the time you hold the exercise and/or the number of sets performed.


Leg Press
