8 Isometric Core Exercises To Build A Killer Core

What is the first thing that comes to mind when you hear the word “core”?

….I would guess, ABS.

But there’s more to the core than the abdominal muscles. The back muscles, obliques and glutes also make up the core.

Having a strong core will make your life easier. We use it almost every movement…lifting stuff, twisting, playing sports……even small tasks like bending and sitting use the core. A strong core will also improve your posture and reduce risk of lower back pain.

There are various ways of strengthening the core. And isometrics is one of the most effective. Just in case you don’t know what isometric exercises are…..they are exercises which involve contraction of muscles without any joint movement. Basically, you tense the muscles to prevent them from lengthening.

One of the most popular isometric core exercises you may know is the plank. But as you’ll see, the plank is not the only isometric exercise that can increase your core strength and stability.

Just because these exercises are not popular, it doesn’t mean they aren’t effective. The mainstream media doesn’t promote exercises which they can’t make money off. No weights or equipment needed, all you need is your body and you are good to go.

Why should I do Isometric Core Exercises?

As I’ve mentioned, there are many core exercises out there. So, you are probably wondering why you should opt for isometrics.

Rehabilitation

Most core exercises cause back pain. Exercises like sit-ups put a lot of pressure on the spine and eventually cause back pain. Isometrics are safer and some will help get rid of lower back pain.

I may add – as you age, some exercises will become difficult to execute. Not isometrics – they are for people of all ages, from beginner to advanced.

Build extraordinary strength

Don’t be fooled by the lack of movement. These exercises increase muscle and strength.

Keeping the muscles tense forces them to give to maximum effort – which makes them grow.

In fact, a study conducted in the 1950’s found that performing isometric exercises regularly, increases strength by 5% per week for period of up to 10 weeks.

No enough time to exercise

If you don’t have time for a 40-minute workout – isometric exercises are a no-brainer. You will finish your sets in seconds.

For a start, aim for a minimum of 30 seconds for each set.

Mental toughness

This is another reason you may want to do isometric exercises. Keeping the muscles tense for 30 seconds is not easy. Pushing through each set, workout after workout will greatly increase your mental strength.

Mental toughness will not only help you push through workouts, but also will also help you control cravings and avoid binging.

It’s always advisable to use a timer when doing isometric exercises. If you don’t, you’ll be giving up in under 10 seconds. Now, all you need is – to learn proper form, a timer, space, and you are good to go.

Glute Bridge Hold

It’s a shame that most folks don’t train the glutes as part of their core workout. Everybody needs strong glute muscles, since we use them in so many movements.

Not only that – glutes are a big muscle group and training them burns a lot of calories. Additionally, physicians recommend the Glute Bridge as a rehabilitation exercise for lower back pain and hip pain.
