How to perform this exercise:
In the plank (can balance on DB’s for more difficulty) position, (1) draw your knee in towards your chest, then extend leg. (2) Draw your knee in towards the opposite elbow, then return and extend leg. (3) Finally, take your knee outward toward the elbow, then extend leg. All 3 =1 rep. Complete 10 reps each leg for 3-4 sets.
The little twist is the leg extension in between the 3 moves. You work your abs and tighten the glutes at the same time. Enjoy the extra burn!
