Start from a seated position on the Swiss ball. Slowly walk out until your lower to middle back is supported by the ball. Your feet should be slightly further than hip width apart. Start with the dumbbells at a 90 degree angle at your elbow, palms facing away from your body.
EXHALE: Slowly push the weights straight up above your chest, keeping them in line with shoulders. INHALE: Slowly lower back to the starting position.
Do NOT perform this exercise on a hard, flat surface after the 1st trimester. If you do not have a Swiss ball, this exercise can be performed on an incline bench. If at any time you feet faint or out of breath, discontinue lying on your back. Make sure to keep your core tight, keeping your hips pulled up toward the ceiling.Muscles worked: Chest, Shoulders, Triceps
