Start seated on the edge of your chair, knees bent, feet flat on the floor. Place your hands behind your head. Twist to the left and hold for 1 count, then turn even further to the left (go as far as you can) and hold for 1 count before slowly returning to start. That’s one rep. Repeat, alternating sides each time, for a total of 20 reps.
Form tip: Keep your spine as tall as you can during your rotation and exhale as you turn, pulling your abs in tighter and tighter during each twist. Inhale as you return to center.
