An exercise program helps build strength and lose weight by increasing calorie burn, preserving muscle mass, and boosting your metabolism. [1, 2]
How Exercise Helps with Strength
- Muscle adaptation: Lifting weights or using body resistance creates small tears in muscle fibers, which repair and grow stronger over time.
- Progressive overload: Gradually increasing weight or difficulty forces muscles to adapt and build greater physical power.
How Exercise Helps with Weight Loss
- Calorie deficit: Physical activity burns energy, helping create the net negative calorie balance required to shed fat. [1, 2]
- Metabolic boost: Muscle tissue burns more energy at rest than fat tissue does, meaning more muscle helps you burn calories all day long. [1]
- Muscle preservation: Working out prevents your body from burning precious muscle tissue instead of fat when you cut back on food calories. [1]
- Afterburn effect: Intense sessions trigger excess post-exercise oxygen consumption (EPOC), keeping your body repairing tissue and burning calories long after you finish. [1]
