If you want to help tone your glutes and inner thighs, try incorporating some toe taps. Start in a basic plank pose, and every two seconds, alternate moving each leg one to two feet to the side. Tap, and return to the starting position. This will also engage your shoulder and lower back muscles. Check out these ways to get better abs with zero crunches.
