Flatten Abs, Tone Arms, and Lift That Booty With a 5-Minute Bodyweight Workout

"Using two of the largest muscle groups in the body — your butt and legs — this dynamic, explosive cardio movement will elevate your heart rate and set the tone for the entire workout!"

• Start with your feet together and hands by your sides.
• Jump straight up, spreading your feet wider than your hips to land with a deep bend in your knees (a squat position). Keep your chest lifted and your hips back (think knees behind the toes).
• Jump back up to the starting position. Drive through your heels as you spring up from each squat.
• Continue for 60 seconds.
