Bonk Fit is the best fitness punching bag money can buy. Our inflatable is super-durable, made from high-quality polyurethane. This is the same material used to make air mattresses and high-performance hydration packs like CamelBak! It's PVC-free so no shower curtain smell.
Setup is easy.
Add Weight. We recommend using water if you’ll be transporting Bonk Fit to multiple locations, events etc. Otherwise, use a solid fill like play-sand. The fill valve is located on bottom. For water fill, squeeze valve to hold open under faucet. For solid fill, push a standard funnel through valve and pour in desired substance. For 1.5FT, add about 4 pounds. For 3FT, add about 7 pounds. For 5FT, add about 18 pounds. Be sure to secure the valve closed by pressing around parameter. Inflate. Use electric pump, air compressor, air mattress pump, inflator/deflator, or bicycle pump. The air valve is located on lower back. Inflate until firm. Slip-on Skin. Lineup side seams of skin with inflatable and wiggle down overtop.
