Don't take me literally with this guys. I'm talking about weight loss. And if losing weight is your goal like me, I think you are also on the path of looking for a fastest way to burn off fat. Cardio exercises are good in burning fat. But nowadays, how come it seemed so hard to lose weight even if I go to the gym? It isn't the same as before. Perhaps age is one factor to keep in mind. Now I'm even thinking that there might be a problem with my program. And so I'm thinking of transferring back to where I used to work out before. Hope that would help.
