Well I'm currently practicing for rugby two nights a week, so I cut my workouts to twice a week. One day an upper body workout and the other a lower body workout.
A. Power - clean or snatch variation
B. Core lift - squat or deadlift variation
C. Supplemental - good morning, squat, or deadlift variation
D. Unilateral - squat, lunge, or step-up variation
UPPER BODY (and Speed squat)
A. Core lift - vertical or horizontal press
B1. Row variation
B2. Pullup variation
C. Shoulder (optional)
My workout is based on a template, so I can just pick and choose different exercises when I have a weakness to address or when I just need to switch things up. The rep ranges wave depending on the slot.
Such as for Power, I'll stay 1-5 reps, Core lifts I will hit a 3-5 rep max most week, with a few 3x6 weeks thrown in, and other than that its pretty much common sense where most lifts stay between 6-15 reps. Deadlifts and squat variations will have lower reps than bulgarian squats, etc.
I'm 17 right now and it's only my first year of rugby so I'm currently in the process of learning and such. But, this setup has been pretty effective for me. You may be able to find something like 5x5 or WSFSB that may work well for you.
