Question: Trouble getting a belt to fit my skinny son with kyphoscoliosis; the Aquajogger keeps riding up and the belt does not stay tight. Will this work?
Document: Fully adjustable; the only issue is getting the cubes lined up in the right spots to allow for movement, and getting them to stay in place once there. However, setup aside this is a great swim belt that has helped my 4 year old explore the pool on his own. It doesn't ride up like your typical swim vest. Recommended.
Perhaps not buoyant enough. It does not seem to hold me up as well in the water, but then this  requires me to work a bit harder to stay afloat while exercising. Could be a better thing in the end. I do like the lesser bulkiness of the belt!
Makes you work just enough to stay afloat. Provides the right amount of buoyancy for a good workout.
I didn't realize this was an aerobic exercise belt but knew it was used as a swim aid so it was a double bonus. I really love that it is so adjustable that I can use it for the exercise and can also be so small to use for my 8 year old son as a swim aid. Our son had just about had the functions of swimming but wasn't confident on his own so this was perfect! It keeps him afloat and gives him the freedom he needs to swim independently.
Instead of those bulky life vests or cumbersome other flotation devices, this belt delivers! Simply put around your child's waist and they can float, trouble free! Just make sure you tuck the extra strap around  and out of the way (don't leave extra strap hanging, don't want it getting caught on anything). Great tool for swim instruction and your little one will feel confident and will be safe while exploring in the water.
We both can swim but lack the stamina that we had when we were younger. The belts that we use have stretchy belts and one piece of spongex that wraps around your back (or front if you desire). These are more comfortable and stay in place but they were more than THREE times the price.All in all these cubed belts are a great swimming aid and can work well for adults and kids that need a bit more "security" or are learing to swim.
We love the belt it has really helped our son with swimming on his own and help with balance. Every parent in swim class has now bought one, it is better than anything that they had at the Y to borrow. Our friend used it in the ocean on vacation.Good for any age kid or adult. My son this a skinny 2 year old and it stays on with a shirt under it.
This belt is reasonably priced, and will fit a huge range of waistlines. Just what I wanted and at a really great price!
A good technique for getting them on and off quickly is to use a ruler. Wrap the belt over the ruler and stick it through the slot in the blocks. Very happy with this purchase and highly reccommend!
This belt was not exactly what I thought I was getting, but only because of my own assumptions and nothing on the sellers part. It is made of inexpensive foam and is a value on par with the cost, but not a great quality product. This is not one of the vinyl covered belts that professional instructors use.
Answer: yes
