This is so easy to use and I picked the perfect size

I am 5'2" tall..........and this Sqoodle fits me perfect.  If you are taller, you probably want the longer one.  I took a water aerobics class before I bought this, and found out how to use it in my own pool.  One of my favorite exercise is riding it like a seahorse and peddling it like a bicycle......... I also bought the Aqua Fit Barbells.  I don't have a negative thing to say about either one of these products.
If you like being in the pool and like to exercise, this product is for you.

The sqoodle holds my head and body weight above water much better than the empty Clorox bottles and water dumbbells used in my water aerobic exercises. I enjoy the added feel of the sqoodle around my back pushing my back higher in the water as well as feeling more comfortable than the Clorox bottles or water dumbbells under my arm pits.

The 3" X 48" Sqoodle works well; however, I believe the 3" X 64" unit would be more versitile.

good for water exercises

If you/your children/your grandchildren ever use a noodle, the Sqoodle is the best - softer, molds to the body, and has greater buoyancy.

I use it when I don't want to get my hair wet, but want kicking and paddling exercise. I've tried many other noodles, but the Sqoodle is the best performer by far!  The kids love it , and use it for water "pony" rides also :)
