Well since you are in-season, you are definitly going to want to make sure you keep the volume down. You might want to try lifting just twice a week, full body each time. You can go fairly heavy (but I would definitly stay away from 1RM’s and try to avoid failure to keep your CNS fresh). A sample program might look like this:
Olympic Back Squats
Incline Bench Press
Close-Stance Parallel Back Squats
Single-Leg Split Squats
Dumbell Incline Bench Press
Rotate those 4 days as it fits in your schedule. The most important thing is to make sure there is a full day between lifting days and any games.
For sets/reps schemes I would use 3 x 5, 4 x 4 or 5 x 3. Just make sure to keep one rep “in the tank” to make sure your CNS doesn’t get beat down. Remember that in-season, less work will often yield better results because of the volume of work you will get at practice.
Make sure to take a week off from lifting every 3 or 4 weeks.
Try that and see how you like it.
