| If you just want to lose fat and not gain any muscle, I don't think it is necessary to do any weight training. Try to run up and down stairs or some small hill, it will get your heart rate up and consume your energy which will help you to burn your fat. Weight training before jogging is also a nice way to burn and get yourself "toned" as you have done allready. As Phate89 said, at some point you'll see what works for you and what doesn't. |
