Targets: Abs, obliques, and legs
- Lie faceup on floor with upper body propped up on forearms, elbows bent 90 degrees. Bend knees so that feet are tucked close to body with pointed toes touching floor directly in front of you.
- Keeping upper body still and toes touching floor, bring knees to right toward floor, then quickly to left toward floor, then right again.
- While knees point right, extend both legs diagonally up to right (as if to kick behind right shoulder) and quickly bend them back down. Repeat, this time bringing knees left, right, left, then kicking left. That's 1 rep.
- Do 2 sets of 8 reps.
