^^^ can i suggest something
the best for volume and having workouts under 45 minutes would be Gironda Style Training.
German volume training is based on Gironda's teachings, so you might as well look up his work.
As a reference point this is what it would look like
Day 1- Chest,shoulders, triceps (1 exercise each and do 6 sets of 6 reps, or 8x8 or 10x10)
Day 2- Legs, calves, abs (same as above)
Day 3- Back, biceps, traps (same as above)
why 1 exercise? because doing that many sets will kill you CNS and therefore requires less work (by choosing 1 exercise)
Gironda also replaced a lot of conventional exercises with his own which I highly suggest you change as well.
bench press becomes the neck press (much better if performed properly)
sit-ups becomes frog sit-ups (search it up)
pull-ups become gironda pull-ups (search it up)
In the end, you die. Just completely superior to a lot of the methods out there.
p.s.: you wait max 30-45 seconds between sets and therefore finish a lot quicker, give your muscles less recoup time and make them fail faster.
p.s.s: take 1 week off after two months of training. you'll need it. AND RESEARCH!!! He is the best.
p.s.s.s: good luck
