Place a cannon in a canoe and put both into the water. Then fire, and... what happens? KABOOM! Id’ bet money on the cannon ball not going far. Why? Because the canoe has a poor base of stability for maximal force production to be generated. Chances are, the canoe will capsize or be blown to pieces.
Would you really try to fire a cannon from a canoe?
Hardly. So why keep pushing your body in training to go to places (KBOOM!) that your shoulders just aren’t strong enough to survive unscathed? Many athletes focus on building the primary moves (for the purposes of my analogy, let’s think of those as big cannons), yet fail to understand the importance of building a bigger canoe (ie. strengthening the stabilisation muscles in the shoulder). It’s typically here that the shoulder gets injured, or you start experiencing pain in the elbows or wrists joints because it’s all linked together in the chain.
