Another leg lift variation, this one challenges your entire lower body as well as your arms and core.
How to do it: Lie on your right side and prop your upper body up on your right extended arm, palm flat on the floor. Extend your right leg straight out and point your toes. Bend your left knee and step your left foot flat on the floor just behind your right leg so that your hips stay stacked on top of each other in your plank position. Shift your weight into your left leg so that your right toe is lightly touching the floor. Squeeze your thighs together as you lift your right leg up to meet your left knee. Hold for 1 count and then lower. That’s one rep. Do 15 reps with your right leg, 15 with your left.
Form tip: Brace your abs in tight and try to keep your upper body still and your hips stacked as you lift and lower your leg.
