If you’re looking for core strengthening exercises, you need to check out the Toe-Drag Plank. It’s one of the core exercises that also engages the muscles in your butt and outer thighs. For this move, start in a side plank position, contracting your core muscles for balance and your feet staggered—your top foot forward and your bottom foot back. Engaging your core muscles, bring your bottom foot up to knee level, return to starting position, and then dip your hips down and back up. If you’re just starting out with this ab exercise, you can skip the dip. Perform two sets of 12 reps on each side.
