Muscle-strengthening activities improve the strength, power, and endurance of your muscles. Examples of muscle-strengthening activities are: 1  doing pushups and situps. 2  lifting weights. 3  climbing stairs. 4  digging in the garden.
Lifting heavy weights is more important to power lifters or those whose only goal is to increase their strength and ability to lift more weight. To build muscle, you have to stimulate the muscle by overloading it with a combination of heavy weights and more repetitions. More reps often necessitate using lighter weights. Muscle responds to the constant overload by getting bigger and stronger.
