Perfect ninja training!
by Taylor Ross (5 out of 5 stars)

There's nothing not to like about these training balls. I was impressed that they came with ties as well as metal clips. I hung the straps from the metal hooks on my son's swing set and it worked just perfect! I had originally ordered extra straps from Amazon and didn't need them to use the balls, but the straps came in handy then I daisy chained them together and hung the balls lower to the ground so my 4 yo son could also have a try! The balls work great hanging form a climbing board also purchased off Amazon. I am going to order a few more of these balls and maybe some rings so we can start monkeying across the whole length of the swing set!

Balls are not the small size as my ninja line (but that's ok to me). Came fast and well packaged!

Love these. Wonderful grip even without chalk. A single one can hold my current 220 pounds of weight. No rough or sharp spots. Great buy and a great price.
