What do you achieve ? A well- toned , sleek body. When you weight- train, you lose fat and gain muscle tone and strength. While activities such as swimming, cycling, jogging, aerobics are fat- burning and improve your cardiovascular performances, it’s weight training that gives you firm, healthier looking body. ( Dieting is not the best route to losing weight because it causes too quick a loss in muscle-tissue. )Weight training also improves metabolism and prevents osteoporosis by strengthening the bones.
