My 13 year old son (8th grade) has been in a strength/speed/agility/hitting program over the winter, no throwing or weight lifting, just keeping in shape. The program is in its last month and last night the fitness trainer pulled me aside to show me how my son moved differently than ALL the other kids. When the trainer called for frog jumps most kids jumped forward like a frog would, my sons legs started wide like a frog but by the time he landed his knees were almost touching and bent inwards towards each other, while his feet were still far apart.
The trainer said this was caused by weak hips and glutes. He said "All the speed and agility training in the world won't work until he can get those built up because right now his running and movements are just ineffective." Then he talked about a few private lessons to teach him to strengthen those areas. He said "I'm not saying he's in immediate trouble, but if he keeps putting pressure on his knee like that it will eventually blow."
When someone says something like he needs a private lesson or *insert bad thing here* will happen I usually assume people are trying to just scam money, or trying to get me to drink the kool-aid, but I did actually see a huge difference in the way my kid moved and the other kids. I can ignore ideas about "He MUST play for team X or else", and even "if he doesn't do THIS he will never get to the next level"...but this is my kids health long term, regardless of baseball, so I'm not going to just ignore this one, or wait until he is hurting. Four years of catching and he has never complained of knee pain, but I know that doesn't mean anything.
Is this weak hips thing for real? Any suggestions?
