SuperStroke StrechCordz Long Belt Slider

We use this to work out in our pool (tied to the fence post and swim in place). It works pretty good but provides A LOT of resistance. I probably would recommend a lower resistance cord if youre going to use this on a regular basis in your backyard pool. The kids love it though and are always trying to compete on who can go further with it on...so a great workout and family fun item!

As a senior citizen, I can now swim non stop for an hour every other day in my small pool.

Our athletes really enjoyed using the StretchCordz and helped identify weaknesses in their swimming. Unfortunately, it only lasted for about 8-10 hours of use. The rubber pulled away from the belt connector while a 140 pound athlete was swimming breaststroke stretched out to 20 yards. I would have returned it, but its been 90 days since purchase. I might buy another one because the product did benefit our swimmers, but would like to see the next one last more than 10 hours.
