I'm Jeremy Shore for LIVESTRONG.COM, and this is exercises for the legs without machines or objects. No need to step into a gym with this great body weight progression that targets the lower legs with stability, strength, and power, all in three moves. Let me show you how. The first is a single leg squat. Stand tall with feet hip width apart, hands on your hips, chest up, abs drawn in. Take your weight onto one foot. Let it hang just beside the opposite foot that's planted into the ground. From there, push the hips back, keeping the chest up, lowering yourself toward the ground, and then drive up. Keep equal distribution of weight through the entire foot. Complete 8 to 12 repetitions on one leg, and then switch feet. Next, for strength, we can do a standard lunge. Hands on the hips, stand up tall, abs pulled in, shoulders back, step. Lead with the heel. Drop the trail knee down till it's a couple of inches off the ground. Push back through the heel. Return to the standing position and switch legs. Make sure the lead knee doesn't move beyond the toe. We can finish with a power move, the squat jump. Extend your hands just in front of you as you drop into a squat, keeping the chest up, butt out, even distribution of weight through the feet. And then we'll explode up, bringing our hands to our sides, landing softly, returning to the squatting position, and repeat. Try these three great body weight progressions to build strength and size in the lower body. I'm Jeremy Shore for LIVESTRONG.COM.
