I had hip replacement surgery 4 years ago, and my Doctor suggested that I take up water aerobics before surgery to firm up my muscles & bone mass. After my operation, I could hardly wait to get back to my water aerobics class. First, I went to the warm water pool to join the arthritis class for stretching and range of motion & then back to the lap pool for more strenuous workouts. Since the water is so buoyant, I have had no problems with my hip joint and love the workouts with my class mates. The instructors are all great with various routines & music which adds to the enjoyment. Another side benefit is that I have lowered my weight & have been able to maintain. I really miss my water aerobics class when I am not able to get to Harbor, where I have made many new friendships with their wonderful staff & members. My wife Harriet also participates in water aerobics & loves it too.
