Alternating Against-Wall Shoulder Flexion

Positioning:

1. Stand with your back against a wall. Your feet should be shoulder-width apart and slightly away from the wall for balance.
2. Position your arms at your sides, relaxed, with your palms facing your thighs.

Movement:

1. Keep your head, shoulders, and lower back pressed against the wall throughout the exercise to maintain proper posture.
2. Raise your right arm straight up overhead in a 'Y' position, keeping your elbow straight. Your thumb should point up to the ceiling.
3. Hold the position for a moment at the top and ensure your shoulder remains relaxed and away from your ear.
4. Slowly lower your right arm back to the starting position.
5. Repeat the movement with your left arm.
6. Alternate between raising your right and left arms for the desired number of repetitions.

Tips:

- Focus on controlled movements to prevent any swinging.
- Keep your core engaged to help maintain balance.
- If you feel any discomfort in your shoulders, reduce your range of motion or stop the exercise.
