7. Bent Leg Rotating Exercise
This exercise will work on your abs and inner thigh. First, you want to stand straight and rest your hands on the rear of your head. This kind of effort gives you more power and brings your focus to the legs. After that, you need to raise your right leg that is bent to your waist. Keep your knee bent and rotate your leg in circular movements. Spin it as much you are able to do for 15 seconds to the frontage. Repeat with the same leg for 15 seconds to the back and move to the left leg. This is a challenging workout and attempts it for strengthening your thighs.
