Q: Is it true that u should only do weight training for 45 mins or 1 hour MAX in order to get good results?Also,it is ok to train 2 body parts each time(different)?Problem is that if i do so i have to spent 1,5 hour or more to do all the exercises needed.If i do one part per day i leave one part of body untrained each week(i need to 5 days this way to do one part every day and i do 4,i have Sunday off and one day in the middle also off in order to rest more cause i tend to train as hard as i can).What is ur suggestion?Iam a little confused how i ll make my program.

A: 45-60 minutes per session is a good guideline in general. An even more useful guideline may be to keep weight training to 2-5 hours/week. Some people, especially younger guys, can benefit higher training load especially for short periods, but those two guidelines probably describe the optimal training load for most people. If you look at my weight training article I have a number of sample programs all of which satisfy these guidelines. Of course you can design your own as well. It is perfectly OK to train more than one bodypart per session and it need not be very many sets. Allowing 10 sets per bodypart (which is plenty) and 2 bodyparts/workout, that's still just 20 sets which you should finish in one hour or even less.
