Hypotrophy vs strength
The goal of hypotrophy training is to increase muscle size. The goal of strength training is to maximize the amount of force produced with those muscles in relation to skeletal structure. Depending on your goal you should build your working differently.
Hypotrophy training should be done maximum 8-12 reps with 30-60 sec rest of 65-85 1RM in order to reach muscle failure.
Strength training should be done with even heavier loads, 1-6 reps of 85-105 1RM till failure. Rest between sets can be 3-5 minutes.
