Another No Gym Muscle Builder
You’ll like this.
Not only is it a highly effective exercise for working both the front and back of the thighs, it’s also great for the glutes (perfect for ladies wanting a firmer backside).
WARNING: If you've never done it before, then approach with caution. This exercise is almost unrivalled in its ability to generate extreme muscle soreness. If you push it too hard you’ll be limping around for days!
