@jdez It's somewhat easy imo.
Pick a goal(strength or hypertrophy. And yes I know there is hypertrophy within strength training but in terms of protocols to follow I've broken it down to 2 metrics)
And apply said goal to compounds.
Example:
Squats, 5x5 at 85%
Deadlifts, I'd personally do one top set 1x5 at 85%( working your way up to your top set of course). Because if your doing 1 top set, not only can you go relatively heavy/max effort, you will be forced to manage fatigue better.
For things like bench and dips, I'd stick in the 6 to 8 range. The idea behind this failure range, so to be within the appropriate intensity needed to activate that growth mechanism.
If you do weight dips with 50lbs and do 3x8, but on your last 2 sets you only get 6 reps, continue this same weight the following week until all 3 sets of 8 at 50lbs is achieved.
I wouldn't worry too much about anything more then 10 reps because you get into this bell curve of higher reps vs intensity, which is the whole point of training in the first place.
Besides, if your doing reps of 20 and up, the intensity will not be there by virtue of the amount of reps performed. Which won't facilitate much of anything other then overuse in your joints.
