3. Scissor Legs Plank
This is a great exercise for working a lot of different muscle groups, like your core, arms, glutes and chest. While giving the inner-thighs a particularly tough workout.
How to do it:
- You need a smooth surface and a couple of towels for this exercise. Begin by assuming the plank position, and put a folded towel under each foot.
- Keeping your upper body stable, slide your feet outwards as far as you can comfortably slide. Then return to the starting position by using your inner-thigh muscles to bring your legs back together.
- It’s a lot harder than it sounds, but really punishes those thigh muscles. 2-3 sets of 15 reps will really test your conditioning.
