Q: How much is it ok to spend at gym each time doing weight training?Is 2 hours ok or too much?Keep in mind that i only do weight training and breaks during this time and not losing time with talking or such things.When i say 2 hours i mean 2 hurs full of weight training.I would like your opinion on this.

A: I feel that for an average person 1 hour per weightlifting session is a good limit with 2-5 hours/week total spent on weightlifting (so 2-5 one-hour sessions per week). A heavy 1-hour weight training session will usually consist of around 20 sets -- this may not seem like a lot, but when working in 6-12 rep to failure range, you should allow at least 2-3 minutes between sets for recovery.

That doesn't mean that some people can't benefit from longer training sessions. But overtraining (doing too much) is far more common among gym enthusiasts than doing too little. What you'll need to do is keep track of your progress and also look out for symptoms of overtraining. If you're finding yourself not making much progress, feeling tired a lot, getting sick, lacking appetite, unable to sleep, irritable, then those are all potential indicators of overtraining. In that case, I would recommend that you take 1-2 weeks off from the gym completely and then come back to a lower-volume program. You can find a number of sample programs with different volumes here.
