Strength training helps you lose fat by building and preserving lean muscle mass, which raises your resting metabolic rate so you burn more calories all day. [1, 2, 3]
How Strength Training Drives Fat Loss
- Increases Resting Metabolism: Muscle tissue is metabolically active. Having more lean muscle means your body burns more energy even when you are at rest. [1, 2, 3, 4]
- Preserves Muscle During a Calorie Deficit: When you cut calories to lose weight, your body often breaks down muscle for energy. Resistance training signals your body to hold onto muscle and burn fat instead. [1, 2]
- Triggers the Afterburn Effect: Intense lifting creates micro-tears in your muscle fibers. Repairing these tissues requires energy, which keeps your calorie burn elevated for hours after your workout. [1]
