Exercise to get trim

Weightloss. Let's face it. To lose weight, we have to burn more calories than we consume. If you just eat less to lose weight, you'll lose weight, but end up lowering your metabolic rate. You burn less calories for the same activity than you once did. Read Dieting to lose weight

Some of the weightloss, also comes from muscle loss.

Muscles burn more calories. Building your muscle tissue would boost your metabolic rate and hence helps you burn more calories for the same activities.

To lose weight, watch what you eat. In addition to that, go do some form of aerobic exercise at least 3 times a week, for 30 minutes each time. Jogging is good. Also do some strength training during your weightloss regiment.
