Original BOSU Home Gym Balance Trainer - 26 Inch Diameter for Core Strength, Stability & Fitness Training - Perfect for Yoga, Pilates, Physical Therapy & Home Workouts

I have found Bosu balls to be really useful for improving balance and coordination. The wall chart really comes in handy for people who have not received good instruction from a gym instructor or physical therapist on the ways that it can be used.I received this Bosu ball today and I'm excited to begin using it. I must note though, that the first one I ordered arrived with a damaged valve. It looked like someone have completely ripped out the valve and then returned the damaged product. The package I received today arrived in a box that had clearly been opened and then sloppily retaped. One end of the cardboard box was torn I expected to find another damaged ball, but this one was in excellent condition, with a pump, two plugs, and a card that contained a QR code that gives access to the manual, warranty, and wall charts.As other reviewers have written, the pump is not really useful. Luckily I have an electric pump with an adapter that fit the Bosu valve. Otherwise, it would have taken forever to inflate the ball using the manual pump that came with the ball, but less than a minute or two with an electric pump. Just don't overinflate it.The Bosu ball seems to be of sturdy quality. The handles on the sides make it easy to carry around and to turn over. Also, it doesn't skid, even on a wooden floor.
