We know squats [1] are good for you. The move helps to build a stronger, better butt and strengthen hamstrings and quads, and through all of this, protects your lower back and knees. But doing the same move over and over can get a little boring, right? Here's a simple way to mix up your squat routine with a straighforward leg lift. Take things up a notch, give yourself a little challenge, and squat your way to a stronger body.

• Stand with your feet shoulder-width apart, feet parallel. Hold your hands out in front of you for balance. Bend your knees, lowering your hips deeply so your thighs are parallel with the floor, keeping weight back in your heels.
• Then rise back up, straightening the legs completely and lifting the left leg out to the side, squeezing the outer glute.
• As you step the foot back into shoulder-width position, squat down again. Then stand up and do a side leg lift on the right side. Lower the leg back to the starting position. This counts as one rep.
