I play with my school and an ex-student who's a personal trainer does a program for us our cup starts this week so we've slowed it down. Before that we were working on power for a month or so (cleans, push-squats, jump deadlifts) over the summer is when we did the 5x5 program. There would normally be 6 exercises 2 would be the big exercises e.g. bench press, bench pull, deadlift, back-squat with a 2x8 warm up obviously followed by the 5x5. It was my first time doing weights and I gained about 10 kilos over the summer and my lifts increases massively. We also mixed in exercises like chin-ups, flyers, body-pulls etc. and to make sure we didn't become big lumps we'd do a conditioning session every other week or so where there'd be around 6/7 stations with something like 100 bench press, 100 step-ups and 50 dumbell rows each side. Absolutely killed but definitely worth it.
Obviously you don't have a summer so you'd have to condense it in someway.
