So we talking about actual time in the gym or actual time working out. Warm-ups and all that other stuff that most guys do before getting ready to move some weight? Also things like gazing in the mirror with a slight flex here and there. Drawning in the not needed lifting belt, an extra notch, to kind of look cool and get that "V" shape. Checking if there is any puss-ahhh around. Even some of the of the 40/50ish MILF kind of look good in a gym. Some at a distance anyway. But like in a bar, mostly looking good nearing closing time.
I'm doing three exercises a workout, in three seperate workout days in a 9 day cycle. Require just about 45- 50 minutes a gym session. Workout #1: BB hack, BP and Hi-pull. Next workout day workout #2: DB Side press, chin and step-up. Workout #3: Dips & SLDL/shrug (a strong shrug when reaching the standing position). Three to four sets each (9 to, at the most, 12 sets a complete workout) and trying for 90 to 120 seconds between sets. And, at the most, 3 to 4 minutes between exercises. Reps are 6-9 mostly. Trying to keep it brief and to the point. Thats the idea is it not? Good Luck.
