Air bike
Fan-resistance bike with moving handles, used for short all-out efforts
The flywheel is a fan, so the harder you pedal the harder it pushes back and there is no gear to hide behind. Arms and legs both work, which is why 30 seconds flat out leaves most people unable to talk. Gyms use it for intervals and end-of-session finishers rather than steady riding. On most gym floors it goes by another name, the assault bike.

An assault bike is one of his own hard conditioning options, next to interval work and running hills. On a bad-sleep day he drops all three and walks instead.

Exercise physiologist · Women Are Not Small Men
Sprint intervals need something you can empty yourself on for 30 seconds, and the assault bike is what she puts women on. She laid out the pairing on Huberman Lab: 20 minutes of heavy lower body work, then flat-out 30-second efforts with as much recovery as you need between them. People think they have four or five in them, she said. Most are done after two.
