Lifting weights helps shed off pounds, but it keeps the weight off too. You burn calories during strength training, and your body continues to burn calories even after. More calories are used to make and maintain muscle than fat, and strength training can boost your metabolism by 15%.
Strength training is also called resistance training because it involves firming up and toning your muscles by contracting them against a resisting force. Your balance and coordination will improve, as will your posture. More significantly, if you have poor flexibility and balance, strength training can reduce your risk of falling by as much as 40%, a vital benefit, particularly as you get older.
Strength training will even elevate your level of endorphins which will make you feel great. It is also a great antidepressant and helps you sleep better.
