The Swiss ball reach, roll and lift increases mobility and flexibility in the upper body, more specifically the shoulders and upper back.
Kneel over a Swiss ball, positioning it under your stomach. Keep your arms bent at your elbows and close to your sides. Extend one arm with your palm facing the floor at head level. This is your starting position.
At full extension, rotate your palm upward as far as possible. Then raise the arm above head level. Hold, return to starting position.
Maintain a tight core throughout the movement.
Be sure to rotate your palm upward at full extension
