Start from a seated position on the Swiss ball. Slowly walk out until your head and shoulders are supported by the ball and parallel to the ground. Your feet should be slightly further than hip width apart.
Start with the barbell centered properly with both arms extended, holding the barbell over your head. Allow your arms to bend to approximately a 90 degree angle at your elbows or just before the barbell reaches your forehead. Slowly raise the bar back to starting position. Do not let your elbows shoot out, keep them pointing straight forward. Try doing 2 sets with 10-12 repetitions.
Make sure to keep your core tight, keeping your hips from sagging.
