Question for the more experienced lifters out there:
Is it more effective if I target a 1 set of muscles (e.g., biceps, chest, legs, etc) 3x/week, 3-4 sets, for approx. 30 minutes with no rest time in between exercises, and another set of muscles (e.g., triceps, shoulders, back, etc.) the other 3x/week, 3-4 sets, for approx. 30 minutes with no rest time in between exercises, with 1 rest day at the end?
Run through a circuit where I target all my desired muscle groups, 3-4 sets for approx. 50 minutes with no rest in between exercises, 4 days/week with 1 rest day in between?
I’ve been doing the first of the two and having decent results, but wondering if the 2nd (or any other suggestions) would be more effective
