Thursday: Quadriceps
Stand with your feet slightly more than shoulder-width apart and your arms at your sides. Keeping your back straight and your abdominals tight, push your butt out as if you were lowering yourself onto a chair (don't let your knees extend past your toes). Rest your hands on your thighs if necessary. Hold for one second. Inhale as your slowly stand up again. Do 12 repetitions immediately following the first repetition of the quadricep exercises described on the previous slide; alternate between the two for a total of four sets each.
