I love this exercise and all the modifications you can do with it. Slow it down and you’ll feel it work the core.
The top videos is what we’d normally aim for in class. Making sure the spine doesn’t arch away from the mat.
Bottom left take the exercise into heel raises. This version takes the pressure off the spine whilst still working the core and getting the hips mobilised.
Bottom right takes the exercise up a level. Adding in the opposite arm overhead adds a new challenge to the exercise.
Which version is your favourite?
