It's common to associate building muscle with weight lifting and fat loss with cardio training. However, by doing so you may be selling yourself short on the potential weight loss results that can be seen from resistance training. The fact is, to burn fat you absolutely have to build strength and muscle.
You experience a temporary spike in metabolic rate in the hours following an intense weight-lifting session. Furthermore, regular weight lifting will help you maintain your total amount of lean muscle mass, creating a permanent increase in metabolism. A larger engine burns more fuel; meaning larger muscles burn more calories and more fat. This creates a physique that is not only strong, but also lean and toned.
Without a properly designed diet that emphasises fat loss and muscle repair, a resistance training routine won't give you the results that you are looking for. Aim for plenty of lean proteins (in the form of chicken breast, turkey breast, fish, low fat dairy products and eggs) to help build and repair muscle fibres following each workout.
