I hit the gym for literally 30-40 mins. I'm in and out. I do 1 muscle group per day with the exception of Mondays which is bis and tris. I do 3-4 sets per workout and 4-5 workouts per muscle group. For example my chest routine might look something like:

-Incline dumbell press 12x12x10x8
-iso-lateral chest press 12x12x10x8
-decline cable presses 12x12x10x10
-machine or cable flys 12x12x10x10

Sometimes I'll only do 3 sets if I feel I've hit it hard enough. I can get all this done in 30 mins. Sometimes I feel like a lot of people train harder than me....maybe not harder, but longer. I've always had a fear of overtraining, whether it's a myth or not, I still try to avoid going over the top. My progress seems to be fine, I'm just wondering if I'm selling myself short by not spending 1-2 hours in the gym destroying my muscles.


***What are your thoughts? I'd like to hear from both sides of the spectrum.....
-the quick and to the point trainers.
-the fanatic spend hours on end and destroy every muscle until you pass out trainers.
