• SIZE 2, Medium/Large, is for people who stand up to 6' tall and weigh up to 200 lbs.
• Locks your shoulder and arms to train/rehabilitate the shoulder in an "abducted external rotation" which trains your shoulders to work against great loads like lifting, throwing, and other overhead motions common in many sports..
• Designed so the weight of the upper arm is supported in the correct position, which isolates and strengthens primarily the muscles of rotator cuff, which is critical to strength and rehabilitation of the shoulder..
• Constructed of a single length of formed steel tubing, and is covered in dense foam padding making it extremely strong but VERY LIGHT IN WEIGHT (under 3 lbs)..
• University study showed the ShoulderHorn was MORE EFFECTIVE for increasing external rotator strength than using dumbbells alone. ("Effects of the Shoulder horn and Lightweight Dumbbell Training on Shoulder External Rotators," published by Journal of Physcial Therapy Science.).

(SIZE 2, M/L, for people who stand up to 6' tall and weigh up to 200 lbs) The ShoulderHorn is for anyone who desires to eliminate their shoulder pain and significantly improve their shoulder strength in any sport (baseball, football, weight lifting, tennis, swimming). Shoulder pain and weakness is due to muscular imbalances caused by repetitive activities with your shoulder. Throwing a baseball, swinging a tennis racket, benching a barbell, are examples. This repetitive activity causes your upper arm to shift out of position in the shoulder joint. This presses against nearby nerves and the shoulder muscles. The pressure and constricted blood flow erodes the strength of the muscles in your ROTATOR CUFF. These rotator cuff muscles are critical for your shoulder strength. Gradually shoulder strength also erodes and shoulder pain develops. CORRECT THIS MUSCULAR IMBALANCE WITH A SIMPLE & EFFECTIVE REHABILITATION PROGRAM! The cure is to counter this imbalance. The structure of your shoulder can be moved back to its natural position with basic stretching exercises and your ROTATOR CUFF strengthened with the SHOULDERHORN. The ShoulderHorn locks your shoulders and arms in the safest and most effective position for "abducted external rotation". Similar to a tennis backhand stroke, your elbow is bent 90 degrees and stays in one position -- while your hand and forearm pivot backward. This trains your rotator cuff to respond to the greatest load during lifting, throwing, and overhead motions. Many athletes have used the ShoulderHorn to successfully to treat their pain and return to their sport. The ShoulderHorn is especially popular with weightlifters to INCREASE THEIR BENCH PRESS. Use the ShoulderHorn with a pair of hand-held weights. As low as 2 lbs for beginners to as high as 20 lbs. for experienced athletes. A small medicine ball or even a can of soup can provide suitable resistance if dumbbells aren't available.
