Question: Does this system work in pools that reach the depth up to 9' in the deep end?
Document: If you have back pain regular work outs can be difficult,with the Aqua Fitness Set, you can do work outs in the pool which reduces the stress on your back and body, the set is easy to assemble. Well worth the price.
I purchased this product and was disappointed that when trying to assemble the dumbells, the end cap slip out. I didn't even get to use it in the water. Perhaps a manufacturing flaw. I will be returning it as I feel the quality did not justify the cost.
I read other reviews and saw that most of the complaints were that the belts ride up and or the end pops off the dumbbells.My friend and I did our usual hour long water aerobic session twice last week and neither of us had a problem with the dumbbells. The belts do ride up but I have used several different belts in the past and they all ride up. I have another more expensive set, $40 for belt/bells and no gloves.
very pleased with my purchase. use it every week in my deep water aerobics class. others in the class paid much much more for their products so I feel very lucky to have found mine at such a good price.
I wasnt crazy about the belt, it kept lifting me up (lol) I loved the hand weights but had to glue them because they kept coming apart. Just had husband put waterproof glue and they have been great ever since. I am sure the end was designed to open and put water in, but it isnt necessary and was frustrating that every time you got into your routine you had to stop because the end came off and the foam end flew up in the water.
I bought these for myself. My wife is now using the gloves and flotation bars as much or more than I do. The gloves are too small for a man's hands, but they fit my wife perfectly. Neither of us use the belt, as our pool is not deep enough to need it. Everything seems to be of good quality. I recommend the set.
was missing some pieces. when you  put the weights in the water the caps come of.
Would recommend Aqua fitness exercise to family and  friends. We re very happy that we chose AFE. Our family now look forward to working out.
Would be perfect if the ends didn't keep coming off of the hand weights. I had to glue them....not long lasting.
Works great. What a workout. I didn't feel a thing till I got out of the water. Helps with my arthritic joints.
Answer: no
