Strength move: Frisbee Cancan
Begin sitting with knees bent and feet on the ground in front of you, holding a Frisbee with both hands. Keeping knees bent, tighten abs and lift feet. Rotate the Frisbee to the left while simultaneously twisting your knees to the right. Pause for a moment.
Straighten your legs, then bend your knees, return to center (feet still lifted), and repeat on the other side; that’s 1 rep. Do 10 reps.
