Squats
Why it is a winner: Squats work many muscle teams -- your extensor ("quads"), hamstrings, and gluteals ("glutes") -- at a similar time.
How to: Keep your feet shoulder-width apart and your back straight. Bend your knees and lower your rear as if you were sitting down in an exceedingly chair. Your weight ought to be equally distributed on three points of your feet -- heel, outaside ball, within ball -- that kind a triangle. Your knees will not keep in line together with your ankles that method, however there'll be less strain on alternative elements of your body. Add dumbbells once you'll be able to do twelve reps with propriety.
