A good exercise you can do at home or the gym.
- Stand with your feet hip width apart, knees slightly bent and abdominals engaged. Have a dumbbell in each hand and have your hands at about shoulder height.
- Exhale and push the weights straight up until the dumbbells almost touch. Avoid locking your elbows. Return your hands slowly to the start position.
Repeat 10 - 12 times, rest, then repeat the exercise sequence as desired.
