We train athletes, but we do not offer ‘athletic training’ due to the cost to benefit ratio. Athletic training by and large is a misguided attempt to combine sporting movements with exercise. An example of this is a baseball pitcher performing pitch-like movements attached to a weighted cable apparatus, and usually in an explosive (read: fast) manner. Unfortunately, all this does is put more strain on the shoulder and surrounding musculature (arm, upper torso).
Talk to a former professional or even college athlete. Most are in some degree of pain from their sport. Even high school athletes deal with knee, ankle, hip issues later in life from the forces encountered during the sport(s) of their youth. There is NO escaping wear and tear - so why make it worse?
Our approach will always be to recommend the athlete practice his/her sport in a fashion as close to actual sport performance as possible: basketball players practice basketball, soccer players practice soccer - a basketball player practicing tennis won’t help his/her basketball skills, it will simply improve their tennis playing. THEN, strength train safely, i.e., with low force. If a shoulder is a delicate/important region for a baseball pitcher, that area should be treated as such - with movements that track joint function and maintain muscular tension. High force exercise can certainly work, plenty of athletes have succeeded over the short term through it’s use, but why risk injury if not necessary? Especially when the athlete will pay for short term success over the longer term?
