If you’re concerned about acceleration, why only one lower body day? Also, if you’re lifting well short of failure and want to increase strength, you may want to increase intensity one day per week, something in the 3-5 reps per set area.
How about…
Mon - Lower Body (3-5 reps per set)
Tue - Team Training
Wed - Upper Body (3-5 reps per set)
Thu - Team Training
Fri - Full Body (Easier day, 6-10 reps per set)
Sat - Match
Sun - Rest
Hits upper and lower twice per week, once hard and once easy. Varies rep scheme. Still only three days in the weight room.
