This variation of plank called side plank leg lift targets your shoulders, waist, abs, back, outer thighs, and glutes.
- Place your right elbow on the ground. Extend both legs out so that your body is in one straight line and you're balancing on the outside edge of your right foot.
- Flex both feet if you can, and either rest your top hand on your upper hip or extend it in the air. Keeping your spine lengthened and your abs engaged, lift your left leg up just higher than your top hip. Then slowly lower it back to your bottom leg.
- Do three sets of 15 to 20 repetitions on each side.
