Recommendations: 2-3 Sets, 8-12 Reps
Sit in the military press chair with your back pressed against the seatback. Grasp water bottles with an overhand grip (palms facing upward). Lift the bottles until they are over your head and your arms are straight. This is your starting position. Slowly lower the bottles until they are in front of your shoulders. Your elbows should flare out to the sides. Inhale during this movement. Push the bottles straight up to the starting position. Exhale during this movement. Repeat for the recommended number of repetitions.
