I have read in magazines that you should only work out your large muscle groups once a week. I am young(18) and if I work them once a week, I don't see any results. I used to work out almost every day and I got big, but I got to a point were I couldn't get bigger. Was I over-working before? I took a break, should I go back to working out every day?

Everyone can have small differences in how their body reacts to training. I have been training for 20 years and I have trained thousands of people professionally in the past 12 years. What I have found to be the best training program is one that works each muscle group twice per week. However, one of the training days should be a little more easier and one of the training days should be hard. Take your legs for example. I would recommend training them twice per week. One of those days would be heavier squats, step ups, lunges, etc. The other training day would be a much easier squat workout or just the step up and lunges. This will provide the best balance in your training program.

You can also train every day as long as you are training on a split program. A split program simply means that you are splitting up the muscle groups so that you don't train the same muscle group 2 days in a row. All of the Fitrex program are balanced properly for optimal results! I even have variations on a weekly basis. Some workout weeks are very hard and some are very easy! This is called periodization. This type of weekly variation will keep you away from being overtrained or having plateu's in your progress.

What you need to do is go to the Fitrex home page and type in the work "periodization" in the search area. Read about periodization and you will see why it is the only way to train!
