Re: Need Cardio For My Stomach
Biking would be great cardio, but your basic idea about your body is flawed. If you have a "tummy" you obviously can't eat whatever you want without gaining *fat*. If you weight has stayed the same, then the bad news is that you're losing muscle while you're gaining the fat and that's causing a decreased metabolsim. Cardio will help, but adjusting your diet will make the big difference. You certainly don't have to starve yourself (nor should you even consider it), but minimizing or dropping the junk food, fast food, sodas and whatnot might be the key. All the cardio in the world won't compensate for a bad diet.
But to answer your question about how much to do, an hour or so is fine. If you do much more than that you may start losing muscle mass, so be careful not to overdo it. 3x a week at least, more if you feel up to it. If you're going for sprints, keep it limited to 20-30 minutes, but go longer if you're keeping a fairly steady, medium pace.
