Resistance Training

Resistance training, also known as weight training or strength training, is a form of exercise that improves muscular strength and endurance by exercising a muscle or a muscle group against external resistance. The external resistance can be dumbbells, resistance bands, water bottles, or even your own body weight - it could be any object that causes the muscles to contract.
