A good way to make sure you routinely do as much as you can to get fit is to take a friend to the gym with you. When you take friends to workout with you they not only make sure you don't slack on going to the gym, but they help motivate you when you're there as well. Working out together also relieves the stress and anxiety of going to the gym alone.
Don't lift weights for more than one hour. Muscles start to become very fatigued after an intense workout that lasts longer than an hour. So make sure that you stop lifting weights before an hour has passed.
If you're trying to bulk up, start out by going until you can't go anymore and then having two cups of chocolate milk. Sounds simple, but a group of those just beginning were studied and it was found that training "to failure" caused a weight gain of 5 pounds in 2 months, but only if followed by a supplement.
