Check out Power to the People by Pavel Tsatsouline or something like that. You don’t have to follow it exactly you can pick two other exercises such as deadlift/bench press.

His program is intended for large gains in amount lifted by doing a little bit more each day for 5 days straight. Since your reps are so low, your muscles do not get tired, and doing near maximal lifts at 90-100% means you won’t get unnecessary bulk. You can find the book in google reader I am sure.

I was able to get to 300 lb. deadlift in about 2 months and felt great but tweaked my shoulder doing overhead press so I stopped (luckily not my pitching shoulder) Next time I try this I might stick to Bench. Anyway absolutely no weight gain, and I felt much lighter on my feet with a DL that high.

My HS Jr. is now DLing 360 for 5 reps, and soon will start the program again when fall baseball is over. He may get to 450 or so this time around with no weight gain and very impressive speed improvement. Plus now he doesn’t have to waste so much time in the gym. Pull the weight, do some box jumps, get out of there and go do baseball or MMA. i.e. by getting strong and not wasting time, he gets to enjoy the play stuff a little more.
