Just had a read of Fighter Magazine. Good article on Hypertrophy for muscle growth. The article explained best to go for 6/7 reps with 80% 1RM, 3 sets, 2.5 minute rest between sets. The progression being adding reps rather than weight each session up to 12 reps then start again. The key to hypertrophy being the 80% 1 RM, the longer rest and time under tension (It did not mention the tempo) High volume training does not have the same effects on Hypertrophy. 
The magazine was the best part of £5.00.So it got left on the shelf. 
Stay Well Stay Happy
