Is running good for someone that just had a hip replacement?

No: Running is not a good idea. Artificial joints wear like the tires on a car. More miles means more wear. Walking is good and trek poles will add 40% to the exercise. Swimming, dancing, golfing, light weight lifting, and cycling are also good. Avoid activities that involve impact stress on joints such as jumping, jogging, running, raquetball, and tennis, as well as contact sports like football.

No: It's generally not recommended although some patients are able to.
