This workout led by trainer Lita Lewis [1] will feature exercises to keep your upper body strong and help improve your posture. Inspired by the real-life workout routine of soccer champion Abby Wambach, this session is ideal for anyone looking for a new go-to arm workout. Grab a pair of dumbbells and get ready to work your arms, back, and shoulders. Throughout this workout, Lita will be taking Gatorade Zero [2] breaks to stay hydrated.
