Stand with your feet shoulder-width apart, your chest tall, and a booty band around your thighs.
Hold your hands at chest level, and bend your knees to push your butt back into a squat like you're sitting on a chair, engaging your core.
Push your thighs outward against the resistance band to maintain tension.
Keep your chest lifted, and do not let your lower back round.
Jump up explosively, swinging your arms backward as you do.
When you land, lower your body back into the squat position to complete one rep. Make sure you land with your entire foot on the ground and with control.
If these are too high-impact for you, try traditional squats instead.
