Whether you have an in-ground pool, above ground pool or are thinking about joining the "Y", water aerobics are a terrific calorie burner. In addition to the calories you burn, you will be giving your joints & and back a favor because of the low impact. I start my pool workout w/ 20 minutes of just walking the edge of the pool, 10 min. forward & 10 min. backward - even that required some time to work up to, walking in water is MUCH harder than it looks. I added one set of 4 laps of freestyle,
then 4 laps of another, plus the first, & worked my way up to all the strokes - freestyle, backstroke, butterfly (tough!), breast stroke (also tough), side stroke on right & left side & dog paddle (really hard). A great workout!
Then you work to drag yourself out of the pool.
