How many sets for muscle growth?
Not counting warm ups, 1 good heavy set is enough to induce muscle growth,
if done correctly to total muscular failure, however, very few people can or
know how to use the 1 set principle correctly so 2 to 3 heavy sets is usually
better to ensure muscle growth stimulation. Anything above 3 sets per
exercise is usually a waste of time and recovery energy.
How many body parts a session?
2 body parts per session is ideal, that way you can fully concentrate on the
body parts and put in 100% effort. It drags on a bit if you have to do 3 and 4
body parts a session, the required intensity just won't be there. Keep it at 2
per session.
How many days a week should I workout?
You should workout 2 to 4 days a week and no more. You simply cannot fully
recover and grow when you are working out 5 and six days a week. It usually
takes 48 to 72 hours for a muscle group to recover from an intense weight
training session. Only until after full body recovery will muscle growth
happen. An every other day routine is good.
