Power—not just strength

Building muscle is not all about strength, . You also need power. "Muscle power, how fast and efficiently you move, is more connected to the activities of daily living and physical function than muscular strength,".

A good way to improve overall muscle power is with your legs, since they are most responsible for mobility. "Doing quicker movements against resistance, like one's own body weight, can be an effective means of developing power," .

For instance, when rising from a seated position, try to do it quickly. When climbing stairs, hold the handrail and push off a step as fast as possible. "It does not have to be every step—begin with one to three steps—but this teaches your muscles to use strength in a more effective way."
