Learn how to build muscle and strength in just 5 minutes, three times a week, by Antony Haynes, sports nutrition expert.

Although true good health involves a lot more than simply having a strong physique, there need not be a contradiction in aiming for both, as having strong lean muscle is in fact one of the key determinants of healthy aging. As we age, we progressively lose skeletal muscle mass and strength, leading to the loss of functional capacity and an increased risk of developing chronic diseases. Fortunately, this muscle loss can be reversed and associated health risks decreased. What’s more, you are never too young (or old!) to start.

The ability of the muscle protein machinery to respond to anabolic stimuli (which promote growth) is preserved up to very old age. [1]. Watch the video here. So what are the exact health benefits associated with an increase in muscle size? Strength training boosts your metabolic rate. Muscle cells burn more calories than fat cells so increasing your muscle mass will increase your resting metabolic rate. That means you will burn more calories, even when you’re standing still! Your metabolic rate is also to do with how quickly the liver breaks down glycogen or fat for fuel. Resistance exercise speeds this process up.

Resistance training reduces age-associated muscle loss. As we age muscle mass naturally decreases. Strength training not only decreases the rate at which this occurs but has been shown to improve function in daily activities, improve balance and reduce the chance of falls and injuries, especially in the older population. [2] Muscle-building exercise promotes the release of growth hormone and testosterone. As the circulating level of these hormones go up, the stress hormone cortisol goes down.

Cortisol is a major promoter of insulin resistance which is linked to metabolic syndrome and increased cardiovascular disease, diabetes and dementia risk. A recent study at the Institute of Sports Science reports that a combination of resistance and aerobic exercises produced greater circulating levels of growth hormone and greater improvements in metabolic syndrome factors in healthy middle-aged women than aerobic exercise alone. [3] Strength training increases insulin sensitivity. When you exercise your ......
