What type of exercise helps build and maintain muscle mass? Resistance training helps build and maintain muscle mass. It makes muscles contract against an external or internal load, such as barbells, weight machines, resistance bands, or a person’s own body weight.

The central training principle is progressive overload: the muscles are gradually challenged with more resistance, repetitions, or training volume. This stimulates adaptations that can increase muscle size, a process called hypertrophy, and can also improve strength through changes in the nervous system. Push-ups, squats, pull-ups, and loaded carries can all be forms of resistance training.

Resistance exercise is useful across the lifespan. It can help athletes develop force, while older adults use it to counter age-related loss of muscle and strength, known as sarcopenia. Adequate recovery and nutrition, especially sufficient protein, support the adaptation process.

Aerobic exercise is valuable for cardiovascular endurance but is not the most precise answer to this question. Flexibility and balance training improve other physical abilities. Resistance training can contribute to those abilities indirectly, but its defining purpose is challenging muscles against resistance.
