There is often a misconception when it comes to working out that more is better. You have gotten spectacular results by working out for one hour 5 days a week, so just imagine how much more you could accomplish by working out for two hours a day for 7 days.
Believe it or not you will most likely end up going backwards by working out more and more. You are not a robot, and you have to give your body time to rest. What some people don’t realize is that you don’t grow muscle while your working out in the gym. Your muscle grow when your outside of the gym, and your muscle cells are regenerating themselves. If you keep pounding your body harder and harder without giving it ample time to recover what will end up happening is that your body will actually start breaking down muscle tissue in order to keep up with the demands you are placing on it. This is what is refered to as “overtraining”. You can look at your body like a sports car. You can run a sports car at redline for a short period of time without doing much damage, but if you run that same car at redline for an extended period of time then engine will blow.
Another factor in your training volume is the demand placed on your central nervous system. This is one of the main reasons that it’s important to keep your training sessions brief, but intense. It’s also the reason that you need to make sure that you get plenty of sleep each night as well as taking entire days off from the gym to recover.
So don’t fall into the trap that more is better. It’s not how much time you put in at the gym, it’s what you put into your workouts when your here. Come into the gym and push yourself hard, but don’t do it for hours on end. Try to limit weight training sessions to 45 minutes to one hour, and the same goes for cardio. When your outside of the gym make sure you are eating a good diet with high quality foods, and try to get 8-10 hours of sleep each night if you can. Unless you are training for a competition don’t come to the gym 7 days a week. Take a day or two off and rest.
