Some of you may know I had foot surgery two months ago. Yesterday my doctor gave me the okay for swimming. After doing twenty laps, I’m a new woman with such a positive attitude, I can’t believe it’s me. Without daily laps, I was getting the blues. Endorphin-happiness is very real. Swimming works practically all of the muscles in the body (if you do a variety of strokes). Swimming develops general strength, cardiovascular fitness and endurance. It does not help with bone density, and I do weight bearing exercise for this. Aerobic exercise gives us a high.
