Step by step instructions
Grab a pair of dumbbells and stand with feet slightly wider than hip width, knees soft, palms facing thighs. Engage abs and push hips back to lower torso until it's almost parallel to the floor (avoid reaching dumbbells below shin level).
Maintaining flat back, engage glutes to bring body back up and immediately curl weights into body and press arms overhead, palms facing in. Try to press the weights up as body returns to upright position in one smooth motion. Return to starting position and repeat.
