Let me explain this simply to everyone, rest is by far one of the most important things someone who has committed to this life style can do. Your body needs to rest completely, at least 2 times a week. Every so often you should take a week off, I do this approximately every three months. Some people fall into the common miss believe that working out more is better. If you can work out more just do it always hit the gym and it must get you results quicker, WRONG! It can have a seriously negative effect on the results you see from your hard work like over training. Your body needs time to rest and repair and grow. You will see much better results resting more and letting your body recuperate then going to the gym every day and working even different muscle groups. Your body needs total rest every few days. I do 2 a week, for begginers you mite want to even do 3 a week. Remember rest is your friend, I know when you start going to the gym and you love it you just want to go everyday and kill your muscle. You have to remember that not going to the gym those few days helps your body, and gets you those results you want.
