According to many online articles I come across, you should only train any one muscle group once a week. Could there any truth to this? I know you wouldn't wat to train one muscle group two days in a row but can you really maximize your results by only hitting a muscle group once a week? I seem to get decent results by training the way i do...
Monday- pecs/triceps (heavy wieght, lower reps)
Thursday-pecs/triceps (light wieght, higher reps)
Now this routine doesn't include legs because i am a roofer and carry heavy materials up a ladder every day. So, could i be getting even better results if i restructured my routine? Could i be over training? Keep in mind i'm not trying to get huge, i just want to be a strong 150lb man that is really toned/cut.
