To get a really effective workout you really need to boost your metabolic rate significantly. But how is this achieved? The best way to burn weight is through resistance training. An effective weight / resistance training session will allow your body to continue burning calories post workout for much longer than a typical cardio workout. Studies suggest that your metabolic rate can be boosted for us to 48 hours after a really intensive resistance workout session.
If you want to improve your resting metabolic rate (your metabolism whilst resting) then you again need to look to resistance training, as it can raise levels by as much as 15%.
If you are serious about losing weight and getting your body into shape you need to combine a healthy diet with resistance exercise. Dieting alone will reduce muscle mass, and this has a negative effect on metabolism. This is why a diet without exercise makes it harder to lose weight effectively.
You don’t need to attend a gym to carry our resistance training. Grab yourself some dumbbells and do simple, repetitive arm exercises or if finances allow grab yourself a cross trainer or rowing machine for your home gym.
