Hello. I am 14 years old, 5'9, 140lbs.
I am a basketball player, and I want to be able to play physical, to play defense, to jump higher, to be stronger, to do every of these things, and not stunt or endanger my growth.
I have absolutely no idea about weight training, I don't know how heavy do I lift, what way do I lift, which part of the body do I lift for, how many reps and sets... I basically have no idea. But I want to start improving my body, and I would need your help. So, do you have any plans for my sort of training, and tips, anything at all?
