So it turns out I might be helping this kid at my gym, it started out with giving him tips like "keep your elbows in" on the bench etc.
He plays either basketball or soccer every single day, and also does some diving.
He's looking to bulk up a bit (very scrawny).
His left knee is weak (something about fluid in the knee) so he uses his right knee to jump etc.
What sort of program / advice would you suggest? Not sure what his best option for gaining size would be here - more full-body or splits? Single-limb work to strengthen the left knee? Of course he would have to get diet in check to make gains with all that sports activity.
