But how can a senior overcome a lifetime of fear of water and get in the pool? Any advice about swimming's benefits, classes or motivation to get me started would be appreciated. I use a walker but feel the water might be freeing.

A. You are right to feel that the water and swimming would offer you great physical benefits and freedom to move. The fact that there isn't any impact is important and many people of all ages take part in water activities.

Water aerobics allows a person to exercise every muscle and every joint in the body all at the same time. Almost anyone, no matter their age, can perform water aerobics. The reason for this is because the water causes your body to be buoyant, thus causing less strain and stress on your joints and muscles.

I know at the club where I teach there are water aerobics classes - all well attended by participants who are recovering from surgery, have other physical challenges, or just enjoy the freedom you mention.

To get past your fear, you may want to purchase a flotation belt that will help you stay afloat with little effort.

If you are truly committed, you may also find an instructor who will help you learn to swim - it will be well worth the time, effort and money. Go for it!
