3 Reasons You Need to Weight Train

Muscle burns more calories. Adding muscle to your body increases your resting metabolic rate which means you burn more calories just sitting on the couch. You also burn more calories after a weight lifting session than you do after cardio. This is because after lifting weights your body uses energy to repair your muscles which burns calories. So even after you are done working out you are still burning calories for several hours.

Lastly it helps keep your bones strong and protects your joins. Aside from an increase in your balance which prevents broken bones and dislocated joints, building muscle actually helps strengthen your bones and joints. It also helps to lubricate the joints by nourishing the cartilage and it obviously helps you maintain a healthy weight which reduces strain on your muscles.
