One of the worst areas on the female body and on any body is the back of the legs. This could be due to the evolution of the desk job. Desks jobs with improper posture can lead to weak hamstrings. This causes even worse posture, and lack of muscle mass. This ball exercise will work your core, hamstrings, and butt. Who couldn’t use that???
You can either hold this exercise OR you can move the hips up and down in 12-15 repetitions. Make sure you squeeze your butt at the top. Always push up from your heals (instead of toes). The stomach should always be tight. Keep your hands flat on the floor to aid in upper body stability.
Add this exercise to your routine to address these problem areas.
