The good news here is that muscle patterning improves within days of starting a weight-lifting program, even without any increase in muscle mass. This explains the 113% increase in strength experienced by the residents of the nursing home in Boston in the previously cited study. In a different study that specifically investigated this phenomenon, 67- to 81-year-old men lifted weights for six weeks while hooked up to electrodes that measured their nerve and muscle patterning (an electromyogram machine). The results showed that the men experienced a 25% increase in the patterning of the muscle along with a 35% increase in strength, all without significant increases in size.
For balance exercise: Do some or all of these exercises every day for best results. Have someone standing nearby to support you if you are concerned you might fall, especially for the ones where I suggest closing your eyes, since this is the most challenging. Speak with your doctor before doing these exercises if you have a balance disturbance or are concerned about whether it is safe for you to do them.
Resistance exercise (weight lifting, calisthenics): To promote and maintain health and physical independence, older adults will benefit from performing activities that maintain or increase muscular strength and endurance for a minimum of two days each week. It is recommended that eight to 10 exercises be performed on two or more nonconsecutive days per week using the major muscle groups.
Pushups: This exercise works the same muscles as the chest press, but it also stretches them while training the core muscles to stabilize your torso and protect your lower back. Not many older people can do traditional pushups, with your hands and feet on the floor. Fortunately, you can make it easier without losing any benefits by elevating your hands on a bench or step, a kitchen counter, or even a wall. Check out the elevated pushup in the video below.
