Many people contract COVID-19 from people who have no symptoms.

It’s estimated that only 30% of American adults do the twice-per-week strength training recommended by experts. Some people think they need special equipment to perform strength-building exercises, while others just don’t know where to start. Adding three simple exercises—push-ups, reverse lunges, and planks—to one’s physical activity twice a week can help improve strength, which may help a person stay independent longer.

Pelvic organ prolapse occurs when the bowl-shaped structure of muscles and tissue that supports the pelvic organs weakens. This allows one or more organs in the pelvis, such as the bladder, uterus, small intestine, or rectum, to shift downward and bulge into the vagina. In some instances, the organs compress the urethra or shift the rectum, producing urinary problems or constipation. Women also commonly experience a sensation of a bulge in the vagina, in addition to pain or pressure, and sex may be painful. The three main treatment options for the condition are pelvic floor physical therapy, a device called a pessary to hold the organs in place, and surgery.
