Resistance exercise, also known as resistance training, strength training, or weight training, is a form of physical activity that involves using resistance to muscular contraction to build strength, anaerobic endurance, and size of skeletal muscles. It is a type of exercise that works your muscle or group of muscles, and it involves exercising muscles using some form of resistance, such as free weights, weight machines, exercise tubing, your own body weight, bricks, bottles of water, or any other object that causes the muscles to contract. Resistance training increases muscle strength by making your muscles work against a weight or force, and when you do resistance training repeatedly and consistently, your muscles become stronger. Resistance training has many benefits, including improved sleep, increased self-esteem, enhanced performance of everyday tasks, and improved body composition. To get the most gain from resistance training, it is recommended to progressively increase the intensity of your training according to your experience and training goals. Resistance training can be done at home, on the go, or wherever you have a little space to move, and it is easily done with equipment like bands, dumbbells, barbells, kettlebells, or whatever heavy item you have at home.
