Locate the pump that came with the ball. It’s probably a flimsy plastic stick attached to a hose. Yes, it looks like a medieval torture device for balloons. Accept it. If you’re like me, you’ll immediately lose the little cone-shaped adapter. Check the carpet, check under the couch cushions, and maybe even inside your shoe. That tiny cone is the secret handshake between you and the ball.
Once you have the adapter, attach it to the pump. Screw it in gently. If it feels like you’re forcing a square peg into a round hole, you’re probably doing it wrong. Read the instructions, but only the pictures. We’re all visual learners when a rubber ball is mocking us from the floor.
The First Few Pumps: A Comedy of Errors
Start pumping. The first few strokes feel incredibly satisfying because the ball is flat. You’re making real progress. Then, around pump ten, your arm will start to burn. This is the moment most people quit and just try to blow it up with their mouth. Do not do this. You will pass out, and your roommate will find you face-down on a half-inflated ball. It’s not a good look.
Instead, switch arms. Use your left arm. If that gets tired, use your right foot. I’m not kidding. Sit on the floor and pump with your heel. It looks ridiculous, but it works. You’ll feel like a genius who has just reinvented the wheel, except the wheel is a floppy sphere.
