Kneeling Side Kick
Get into a side plank position, with your left knee and left hand on the ground and your upper half lifted. Lift your right leg up straight, so it’s either parallel or slightly higher than your right hip.
Keeping your foot flexed (important!) and your leg straight and at the same height, kick forward as far as you can, and back to start.
Repeat for 12 reps total and switch sides.
