sorry i couldn't help you because i'm trying to come back from a back injury myself. will somebody help both of us out if you can?
ok, i hurt my back a year and a half ago. i ran full speed trying to track down a ball. while i was running full speed, my head began to drop forward and i lost balance. i fell down with my back crashing to a pole fence kind of thing but my back hit the pole straight on while i was down. the impact was pretty big cause i'm pretty fast and reckless kind of player. actually, i consider myself the fastest in my park.
i have been swimming for the last seven months almost everyday, at least 5 days a week cause people told me swimming is good for my back. did some stationary bike the last month but just 3 days a week cause i don't wanna lose too much weight cause i'm trying to gain weight. but when i play tennis, i still feel uncomfortable when i play an intense rally. ok, my question is can you swim before playing tennis? cause i tried it before and my back feels great. but someone i know who is a trainer told me that if i keep doing that, it's like a drug. i'll always have to rely on swimming when i play tennis and that's not good. please tell me if that is true and what can i do to get back my lightning speed. people rarely hit winners against me before the injury, now i lost my explosiveness.
somebody please help me and the OP.
