Ball crunches are great because you are able to work through a larger range of motion than when you are on the floor. This makes it harder and more effective because we all know that harder is usually better when it comes to Xercise!

This routine will also teach you the X Gym key principle of Time Under Tension, which gives you endurance and that’s important when it comes to core work because then you will have a functional strength you can actually use in the real world, instead of just an ordinary every day “gym strength” that might be impressive in the gym, but has no real practical application to doing active, fun stuff outside the gym.

If you would like more unusual, safe, effective Xercises like this, check out our Eastside X Gym or our X Gym app today!
