The ARM STRONG is the gold standard for arm strengthening and mechanics. The product uses resistance tubing that allows for progressive resistance. The tubing is constructed of latex and can be safely and repeatedly stretched to 2.5 times its length. Often referred to as surgical tubing, resistance tubing, rubber tubing, or exercise tubing.
The tubing alone is only part of the secret to the success of the ARM STRONG. The patented “Real Feel” Rotating Ball handle, together with the resistance tubing, makes a sport specific exercise trainer. The handle creates two important features.
#1 ARM STRONG becomes, as often referred to as, the “universal gym of tubing products”. With the light, medium,and heavy tubes, there are 7 different combinations and resistance levels. A player can change the resistance based on the difficulty of the exercise or as one builds strength, simply increase the resistance.
#2 The “Real Feel” Rotating ball handle provides a natural motion when performing the throwing exercises. The resistance is specifically focused on the muscles involved in throwing because it completely emulates the throwing motion all the way down to the fingertips. 
*** IF ONLY TUBING WAS MERELY WRAPPED AROUND THE HAND, AS SOME USE IT, IT PUTS UNDUE STRESS ON THE HAND WRIST AND ELBOW. IT CAUSES THE HAND TO BE TORQUED AND PUTS THE WRIST IN CO-CONTRACTION (A LOCKING POSITION) TO FIGHT THE TORQUE.*** Try it for yourself, if you have tubing, simulate the throwing motion and stop when your hand is in front and see if your hand is in the true throwing position. Also, feel the stress at that point and where you are experiencing it. If it’s not on the shoulder then it’s not much benefit. The ARM STRONG is the gold standard and used by thousands of players, trainers, and therapists.
