While cardiovascular exercise is a great way of burning the fat, adding a little strength training to your workouts will earn you extra calories every day. You'll even be burning extra calories while you're sleeping or sitting on the couch watching Eastenders.
Aerobic exercise may burn a few hundred extra calories for dinner, but for every additional pound of muscle you gain, your body burns around 50 extra calories every day of the week.
Research has shown that regular resistance training can increase your Basal Metabolic Rate by up to 15%. So for someone burning 2000 calories per day, that's a potential 300 extra calories, more than a Mars bar, burned every single day.
Do not be disheartened if initially you seem to be staying at the same weight or gaining slightly.
Muscle weighs more per square inch than fat, so whilst your weight might not be dropping very quickly, your clothes are feeling baggier and you are seeing a healthier, slimmer and better toned you in the mirror. That's far more important than anything those nasty scales have to say, any time.
"Is weight training right for women? I loved Terminator, but being 5ft6 and female I'm not sure Arnie's muscles would suit me."
Weight training is just as suitable for women as it is for men. Many women are wary of taking it up for fear that increased muscle means increased masculinity, this is not the case.
Testosterone is a very important factor in the development of muscle shape, so as women have very low levels of this hormone their muscles develop differently, meaning a little resistance training will not lead to a bulky, butch physique.
"I'm not getting any younger, shouldn't I just stick to low resistance exercise to avoid injury?"
No in fact building a little extra muscle can actually reduce the risk of injury.
Strong muscles, tendons and ligaments are much more capable of withstanding stress, and the improved flexibility gained by strength training also reduces the likelihood of pulled muscles and back pain.
Weight training is an excellent way of combating several symptoms we all face as we get a little older.
Resistance exercise can reduce bone deterioration and build bone mass, preventing osteoporosis.
Working your muscles can also inhibit the affects of sarcopenia, the age related loss of muscle mass, strength and function. After the age of thirty there is a loss of 3-5% of muscle mass per decade, making day to day tasks gradually harder to perform and slowing down metabolism - increasing the risk of weight gain.
