This combination move helps you get the most for your time by grouping two standard moves. To get started, stand holding your dumbbells at your sides, with your palms facing forward. Step forward with one leg and lower yourself until your opposite knee nearly touches the floor and your front thigh is parallel to the floor. As you step forward, curl the weights, keeping your elbows down and close to your sides, then push yourself back to starting position. On the next rep, step with the other leg. Perform this exercise slowly. To challenge yourself, add an overhead press when you return to starting position.
