Coming as someone who has had an RC injury, I would say direct training is a must, especially as you continue to grow (and can lose flexibility). I was working my RC almost every day with exercises learned in PT post-injury, but now I do light warm ups at home with no weights at all. Every so often, I through in light dumbbell work-- 8 pounds at most. It's helped tremendously.
A bad RC injury can knock you out for month. Be careful.
