Isometric Sit Up

Strong Core

Maintaining a strong trunk/core/abs is beneficial for all aspects of strength and sports. Having a strong trunk can help you squat strength by maintain an upright position in the squat and even help with speed by maintaining your sprint positions.

A simple trunk variation our performance training coaches like to work into the program is the “Isometric Sit Up”. This is a great variation abs strengthening exercise that’s simple to do and is a great way to increase intensity if you’re not yet prepared for weight bearing sit ups (this can be determined by your personal trainer or performance coach).

How To:

Simply lower yourself down half way while maintaining a flat back. Once you hit the half way marker hold the position for 3+ sec, maintaining a flat back and neck neutral.

Reps/Sets

We recommend 5+ reps, as long as you’re maintaining position. If you can not maintain a flat position you’re probably best to keep strengthening your trunk with other methods, such as planks.

Sets= 3+

*As with any exercise please be careful. If you feel any pain, this exercise may not be suited for you. And if there is a past injury, it maybe best to either stay completely away or slowly introduce the movement to see how you adapt.

Train smart,
