Forget the adductor machine!
This exercise works the butt, hips, legs, and both the inner and outer thighs.
Tip: Stick your butt out so you're able to sit into the movement.
Stand with your feet hip-width apart, hands on your hips (a). Take a big step to the side with your left leg, then push your hips back, bend your left knee, and lower your body until your left knee is bent 90 degrees (b). This should take two seconds. Push back to start. That's one rep.
