Why do muscle conditioning exercises ?
As we age, our lean body mass shrinks and our metabolic rate – the rate at which we burn calories – slows. We can eat exactly what we did ten years ago and weight the same, but have a higher body-fat percentage. More fat carries risks including diabetes, arthritis, back pain, high cholesterol and high blood pressure. It can even raise your risk for certain cancers. Strength training lowers body fat by building lean muscle mass; 20 minutes, two to three times a week, is all you need. Get body fat measured at a gym or health club – that number is much more important than your weight.
