How to Increase Cycling FTP
6 min read
Raise FTP with sweet-spot and threshold density, a short VO2 dose, and a retest — not a 12% promise in six weeks. Garmin, Strava, Whoop, and intervals.icu keep the block honest.

A Power goal in N+One is usually FTP watts or FTP W/kg. That is a number you can retest, not a vibe. ChatGPT will offer 4×8s forever. The twist is the connected plan: Garmin, Strava, Whoop, and intervals.icu so a failed interval set and a bad recovery score change the next session instead of you guessing whether to “push through.” can move the number without a lab; a planned retest still keeps the goal honest.

FTP is an estimate of the power you can hold for about an hour, usually tested with a 20-minute protocol or modeled from rides. Coggan power levels hang off that number. Trained riders more often see 3–6% in a focused 6-week builder than marketplace claims of 8–12%. Beginners can see more because the first block is also a habit block.
If W/kg is the metric, you have two levers: watts up or mass down. Watts up is this article. Mass is a body-composition goal with a medical-clearance mindset — not a crash on race week.
Set start and target watts in Settings → Goals. A 15–25 W target over 8–12 weeks is a plan. A 80 W target over 6 weeks is a story.
A classic builder is 4–6 weeks of sweet spot (roughly 88–94% FTP) and threshold (around 95–105%), then a short VO2 week, then deload and retest. Over-unders teach you to recover just below threshold. Tempo riding is not the same as sweet spot — living in Z3 all week is how FTP stalls.
Two quality days plus endurance is enough on 6–8 hours. Low-volume riders (~4 h) should keep sweet spot and drop the heroic VO2 pile; see also time-crunched goals.
VO2 without burnout is the ceiling tool when threshold work stops moving the number. It is a second article, not week one of every FTP goal.
Keep reading. The work: sweet spot, threshold, then a little VO2 is the core. Sibling guides and Goals in N+One keep the thread.
Week 1: baseline 20-minute or a known modeled FTP. Week 6 or 8: same protocol, similar time of day, similar caffeine. Do not compare a fresh indoor 20-minute to a tired outdoor climb.
If the retest is flat but long rides improved, you may have a durability win that FTP does not show. Decide whether the primary metric is still watts.
Readiness vetoes the test day, not the whole block. Morning readiness can move the test 48 hours.
Upload over-unders to the trainer or head unit: Garmin/Wahoo. Strava captures the outdoor threshold ride. Whoop tells you when ATL spiked. That is how the coach works — not a spreadsheet you abandon after week two.
Easy days stay easy or the threshold work cannot land. Seiler is the citation even inside a “threshold-heavy” block: most minutes are still not threshold.
