"This is a full-body variation masked in ab work," said Huffman. The upper and lower half of the body are meant to stay in flexion while they cross back and forth and the center stays glued to the mat. Being careful not to wobble in the belly as you move back and forth five times on each side."
- Start with knees to your chest, head lifted, and hands behind your head, with your upper back off the mat.
- Engage your abs, and use them to draw your right shoulder towards your left knee as you twist slightly to the left.
- As you twist, extend your right leg out at an angle.
- Switch sides as you breathe, reaching your left shoulder toward your right knee as you twist to the right and extend your left leg.
- Repeat for 60 seconds.
"Want more of a challenge?" said Pena. "Try with straight legs!"
