Strength training helps to keep your metabolism ticking along at a fast rate, so that you burn more calories every day.
Studies show that your metabolic rate slows down as you age, because your body is steadily losing muscle mass, beginning at around age 35. Unless you make an effort to maintain – and hopefully build – your muscle mass, your body composition will gradually become more fat and less muscle. Every if you stay the same weight, you’ll be bigger – fat occupies more space than muscle of the same weight. Regular strength training two to three times a week looks after your metabolism and your muscles, plus you get an immediate benefit because you’ll burn more calories for 24 hours after a strength workout.
