If sd has no influnce but helping you to recover, its better for me to do 10 days sd than 14 days sd. Am i right? Another question. Lets say my muscles grow with 20 rep range, So it better for me to do 20 reps than 30 reps. Because if i start right away on 30 reps, my muscles would get use to that rep range faster. So starting from 20 reps and gradouly getting to 30 reps range after a few cycles is the best thing for me to do. right?
