And, while there’s no such thing as strength training for the penis, there is an exercise you can do to help keep your erections as firm as possible, says William Hartman, M.D., codirector of the Center for Marital and Sexual Studies in Long Beach, California. The exercise is often called a Kegel for men, and it works by strengthening the pelvic-floor muscles, the ones situated right beneath the base of the penis. First, find the right muscles: They’re the ones you use to stop urine flow. Squeeze the muscles tightly for three seconds. Then release. Start from a few and work up to 200 per day.
Just as important as keeping fit is continuing to have sex, not just for physical reasons, but for psychological ones as well. “Giving up on sex at any age can be symbolically giving up on all of life,” says E. Douglas Whitehead, M.D., a New York urologist specializing in treating impotence. “It can drain vitality out of your marriage, your work, your sense of physical well-being and many of the other satisfactions that the second half of life can bring.”
