I'm looking to get the fastest results and I'm looking for advice on how much volume to use, specifically on sets and repetitions. I just started training after a two-year break and I would like to regain what I had before. I was very strong before, benching over 300 lbs.
Muscle memory is real bud, that strength comes back fast. Start around 10 to 12 sets a session, 8 to 12 reps, and add a little each week. Let your tendons catch up before you chase 300 again.
