The medicine ball curl and press targets the biceps as well as the shoulders. Because you're doing this one arm at a time, you'll also engage the core to keep your spine straight and your balance intact. You can do this from a seated position, as shown, or from a standing position.
- Stand or, if you're sitting, engage the abs and sit up with good posture.
- Hold a medicine ball in the right hand down at your side.
- Balance the ball in your hand as you curl the arm up in a biceps curl.
- At the top of the movement, push the arm out and up, engaging the shoulder.
- Bring the ball back down and then lower the arm to starting position.
- Repeat for 1-3 sets of 10-12 reps, switching sides for each set.
