How to Inflate the BOSU Balance Trainer

BOSU is an acronym that stands for "both sides up." The BOSU ball has a flat, circular base with an inflatable dome. Use the BOSU with the dome side up or down to do a variety of strength, agility, balance and aerobic exercises. After buying your BOSU ball, you have to inflate the dome. Most BOSU packages include a hand pump, but you can use any bicycle or air pump. You need a standard air pump nozzle -- not an air pump needle, which is too small for the BOSU inflation hole.
