Frequently asked questions

How do I improve my W/kg?

Both routes work: raise your FTP (through structured training, especially sweet spot and threshold work) or reduce body weight (through diet). For most cyclists, training to raise FTP is the more controllable variable.

Is 4.0 W/kg good?

4.0 W/kg is a strong recreational-to-club cyclist — comfortably completing sportives, competing in local races and keeping up with most club rides. 5.0+ is competitive amateur level; 6.0+ is elite.
