To tell you the truth I don't think its that bad of an idea to get into the groove of things. When I had to quit for a while I find that my body gets a good kick start when I do a full body workout for a couple of weeks. Now this doesn't mean give it all you have and hurt yourself; do a moderate workout!

If your more advanced this won't do much but make you overtrain.... Listen to your body, no one is the same. Get as much basic knowledge and give it 4 weeks and adapt to it. Good luck!
