VO2 max intervals are the single fastest way to raise your FTP. But most riders sabotage them in the first 30 seconds.

The mistake: going as hard as you can on rep one, then fading and limping through the rest. You suffer more, you blow up, and the adaptation never happens.

The fix is pacing. Go as hard as you can hold for every rep, so your last interval looks like your first. Coach Frank Overton breaks down the right way versus the wrong way with the power data to prove it, plus the two go-to VO2 sessions he prescribes most.

Your FTP, the number behind every training zone and workout, usually means scheduling a painful 20-minute test. CoachCat skips that. It reads your hard efforts, races, and group rides automatically, finds your FTP, and updates every zone in your plan. No test day, no math, no guessing.

Build your plan with CoachCat, put in the work, and if you're not faster in six weeks you get every dollar back plus a call with a coach to figure out what happened.
