Rest

Knowing when to rest is key to exercise.  Remember this, your muscles grow and gain strength only when you are resting.  The exercise time is when the muscles are tearing, so you must rest.

When I first started this adventure, I exercised six (6) days a week.  When Sunday came around, I was done, but come Monday, I got back into it.  I was a mad man, completely gonzo with my new found lack of pain in my hip.  As far as I was concerned, I was given a new lease on life without pain and by golly I was going for it. However, after six months I stopped seeing gains; I plateaued. 

I took a week off to just relax and go on vacation with my family, maybe it was more.  When I returned, the first couple of days were tough, but I noticed that I felt stronger and lighter on my feet.  That's when I started coming to the conclusion of the need for rest.  Now, my schedule is four days of rest from weight lifting each week, but I still work cardio five or six days a week.

Try getting some rest each week from weight training, but keep the cardio up.
