Shoulder Stability and Strength for Throwers
Why Shoulder Stability Matters
The shoulder provides the large range of movement needed to throw, but its shallow socket offers relatively little natural stability. It relies heavily on the rotator cuff and the muscles controlling the shoulder blade to keep the joint centred and guide the arm safely.
During a throw, these muscles help transfer force from the body into the implement. After release, they must also control and slow the arm. Good shoulder stability therefore supports efficient technique and helps reduce unwanted stress on the shoulder and elbow. Stability does not mean stiffness: a thrower needs a shoulder that is both mobile and well controlled.
Rotator-Cuff Control
Resistance-Band External Rotation
Keep your elbow tucked against your side and bent to 90 degrees. Rotate your hand outwards without turning your body or lifting your shoulder. Use a light band and return slowly.
Resistance-Band Internal Rotation
Keep your elbow against your side and draw your hand in towards your body. Keep the shoulder relaxed and control the band in both directions.
External Rotation at Shoulder Height
This is called “rotator-cuff curls” in the original programme. Hold the upper arms level with the shoulders and the elbows bent to 90 degrees. Rotate the forearms upwards without allowing the elbows to move. Use very light dumbbells.
Shoulder-Blade Stability
This is the programme’s “prone raise.” Lie face down and lift the arms diagonally into a Y position. Lead with the thumbs, keep the neck relaxed and begin the movement by controlling the shoulder blades.
This replaces the less familiar name “dorsal raise.” Lie face down with the arms out to the sides. Draw the shoulder blades gently together and lift the arms without shrugging.
This is a safer and easier-to-learn version of the programme’s diagonal row. Brace the body, pull the elbow towards the ribs and finish by drawing the shoulder blade back. Do not twist or jerk the weight upwards.
General Shoulder Strength
Alternating Dumbbell Overhead Press
Press one dumbbell overhead while keeping the ribs down and the body upright. Lower it under control before changing arms. Avoid leaning sideways to move the weight.
Lower the dumbbells only as far as you can while keeping the ribs and lower back controlled. Do not chase extra range by allowing the back to arch or the shoulders to become uncomfortable.
Raise the dumbbells in front of the body to approximately shoulder height. Keep the trunk still and lower the weights slowly.
Raise the arms outwards with a slight bend in the elbows. Stop around shoulder height and avoid shrugging. This exercise usually requires less weight than expected.
How to Use These Exercises
Begin with very light dumbbells or a light resistance band.
Perform every movement slowly and through a comfortable, pain-free range.
Quality is more important than weight or repetition numbers.
Do not attempt every exercise simply to accumulate repetitions; select an appropriate group with your coach.
Increase resistance gradually because tendons and joints adapt more slowly than muscles.
Stop if you experience sharp pain, instability, numbness or a noticeable loss of strength.
Athletes returning after illness, surgery or transplantation should follow the advice of their medical team and coach.
