I bought one of those BOSU things because I thought it would help prepare me for x-country ski season. This morning I decided to pump it up and try it out. What a frustrating experience!
The very second you take the pump nozzle out, the air comes rushing out and you scramble to get the plug in, only to find that too much air has come out in the meantime. Then you have to find a pair of plyers to get the plug out again to put more air in, which means starting from scratch. If you try to hedge by putting a little more air in than is recommended, the pump shoots off altogether.
I've got enough air in to use it, but it feels much softer than the ones at the gym. Any suggestions?
