My 1st thread here was in early August as I was taking my son into off season with some goals to improve mechanics and increase overall athleticism, mobility, strength, etc…
At that time his physical stats:
14 years 7 months
Cruising 79-80 fastball
15 years 2 weeks
6’1 182 lbs
30 days to 1st High School Tryout
In September and October he worked out with a personal trainer focused on hip mobility, overall biomechanical balance across all movements and general athleticism. This was 16 sessions over 8 weeks. During this same period he was working out with the baseball off season program at school 5 days per week on fielding, throwing and conditioning.
November and December the baseball off season program at school shifted focus to strength and weight gain through Olympic lifting.
One of our primary goals in improving his hip mobility was to allow him to land more closed and still get his hips through. Due to a lack of mobility and flexibility he was landing 20 degrees open which put additional torque on his arm.
Yesterday we were able to get his 1st bullpen session in since October. Here are a couple of clips. Any feedback, thoughts or comments are welcome.
