Most don’t think past a 6-pack and think about their core as a whole structure. This exercise helps to strengthen aspects that are normally missed.
Lie on your mat face down with arms and legs extended. Inhale deeply and as you exhale squeeze your core/glutes to lift both your arms and legs off the ground. Inhale again and you lower back down to the starting position and exhale to repeat.
You can perform this exercise by doing several in a row, doing holds at the top, or repeating for time. Listen to your body, respect where it is at, and challenge yourself to work beyond your limits.
