From the number of YouTube videos out there, you’d think this product was readily available for purchase. But I couldn’t locate any vendor on-line, so perhaps this is the “viral” marketing pre-launch.

An interesting device nonetheless, although it’s not immediately obvious how you get back on it if you fall off in deep water and with no dock or boat in sight. Looks like great exercise though.

P.S. My physio wife laughed when she saw this: “Not for anyone with back problems”, she said, “This will quickly destroy your discs with the repetitive compression cycles”. Killjoy!
