It’s great that you are paying attention to your strength/power levels at an early stage in your ball career.
As a b-ball and conditiioning coach I’d like to add my 2 cents. First, do not make the mistake of becoming obsessed with lifting for lifting sake. I have worked with 2 players who sacrificed their skill training and court time to the weightroom. They got real strong. But their abilities on the court fell-off considerably, performing below where they did the previous season. They struggled during their senior seasons and lost out on some nice scholarship opportunities.
Unless you are unusually gifted as a basketball athlete, and you may be, please spend the bulk of your time dialing in your ball skills.
Second, make sure you condition the anaerobic and aerobic qualities that a player must have in order to perform at a high level during every period of a game, and during the course of a long tournament. I frequently see physically strong players who play the game like football players: they get a nice rebound, get out on a break, flush a nice dunk but have to walk back up court because lactic acid has kicked them in the ass. These guys are only good for a couple of plays at a time.
That being said, I have used the WSB program for 3 players. It appears to be working for adding size and decent strength levels. The suggested weekly template for scheduling workouts has also been working well in terms of coordinating practice with lower body workouts. In addition, the single squats with DB’s have been great for my athletes’s leg strength, balance and injury-proofing against groin pulls.
In the summer I have some players on CS Sloan’s Frequent and Furiuos program, with a few small changes. One player’s vertical jump increased 6 inches in about 2.5 months on that one!
Sorry for the rant but, I have strong opinions about training for the game. And I believe there many more players who could play college ball at some level if they worked a lot harder at developing the various specific ball skills while strengthening their bodies.
