Is it ok to workout more than one hour or will that start to burn muscle?!


Question:

Answers:
The personal trainer at my gym recommended to me that while I am trying to tone up, I should avoid doing more than 30 minutes of cardio twice a week. (I thought this sounded rather low.) He said doing more than this would be counterproductive and would destroy the muscle tissue you were trying to build.
Personally, I do 30 minutes of cardio every time I do weights.

Other Answers:
it is ok. you will gain muscle.

Eat correctly and you will gain muscle.

Depends on what your meaning of workout is. If you mean lifting weights for more than one hour then that is ok. As long as you eat enough to compensate for the extra calories burned.

i dont think it will burn muscle, it will burn fat

an hour is good because if you do it everyday constanly you will gain muscle so work out every other day or every other two day that should help you loose weight

Yes, it is ok, but remember the majority of your muscle will be built when you are NOT in the gym, so if you can work out sufficiently in an hour to and hour and a half it will work the best for your body. Next step is to ensure that you eat the best that you can and get 7 to 9 hours of sleep a night!

Depends on how intense your workout is. If you are trying to burn fat, you will get the most benefit from low intensity workouts lasting longer than 90 minutes, as that is considered the point at which you are burning more stored energy than blood energy.

1. you can't burn muscle, you can gain.
2. IT's ok as long as you don't strain. if you feel your dying then stop

I have never heard anything about a workout burning muscle. Working out burns fat and builds muscle.

One hour is generally is the time frame in which I workout. You can't burn muscle nor gain it. You merely increase the mass. It is better to work on 2 specific muscle groups in one hour sessions. Like triceps and back, or biceps and grand pectoral.

By "burn", do you mean the body consumes muscle tissue to continue the work out? If we were to "burn" muscle after one hour, we wouldn't have marathons. Just by training for one you would whither away to nothing. There is plenty of free floating fuel in your blood for your muscles to consume during a work out. After those levels drop, your body starts to breakdown fatty tissue (uniformly throughout your body). Any burning sensation you experience is acid build up. Eat bananas, drink lots of water and alternate heavy and light work out days.
