WHY HAS MY FTP STOPPED IMPROVING?

By Anthony WalshRoadman CyclingUpdated 26 May 2026

ANSWER

FTP stops improving for five main reasons: intensity distribution drift into the grey zone, stale training without progressive overload, skipped recovery weeks, chronic under-fuelling of hard sessions, or too little variation in stimulus. Most plateaus are fixed in 6–8 weeks with one targeted change — usually fixing the easy rides first, then adding a fresh stimulus.

KEY TAKEAWAYS

Grey-zone riding is the most common hidden plateau driver — it prevents recovery without driving adaptation.
Progressive overload matters: the same sessions week after week stop being a stimulus after 6–8 weeks.
Under-fuelling threshold sessions blunts the training effect before it can translate to FTP gains.
A periodisation change — adding a VO2max block or a longer base phase — often breaks a plateau that interval tweaks cannot.

WHO THIS IS FOR

IS THIS YOU?

The structured rider whose FTP has been static for 3+ months

You're doing the intervals, showing up consistently, and the number refuses to move.

The rider who has hit a level-specific ceiling

You've made good gains over 2–3 years but progress has slowed to near-zero.

THE ROADMAN VIEW

Anthony hears this one all the time: 'I'm doing the sessions, I'm consistent, and my FTP hasn't moved in four months.' The frustrating truth is that consistency alone isn't enough if the training has gone stale. The body adapts to a stimulus and then stops adapting. If you've been doing the same 2×20 at the same percentage for eight weeks, your body figured that out six weeks ago.

The fix is usually simpler than people expect. Most plateaued riders are dealing with one of two things: either their easy rides have crept up into zone 3, robbing recovery and dulling the hard sessions, or they've been running the same block template for months without a periodisation shift. The first fix is to actually slow down the easy days — which feels wrong but works. The second is to change the stimulus: swap a threshold block for a VO2max block, or come back to a longer base phase before the next build.

Dan Lorang's view, which comes up in his Roadman appearances, is that at some level of development, more training of the same type yields diminishing returns. The athletes who keep improving are the ones who vary the stimulus thoughtfully — different block structures, different interval types, occasionally cutting volume to let adaptation consolidate. The plateau is your body telling you it needs a different question.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Dan LorangHead of Performance, Red Bull–Bora–Hansgrohe; coach to Jan Frodeno
Adaptation requires progressive overload and periodic change of stimulus. Repeating the same training block indefinitely stops producing adaptation — the training has to evolve, either in structure, intensity profile, or volume distribution, to continue driving improvement.

A common plateau mechanism in trained amateurs is intensity drift — the gradual migration of easy rides toward the moderate zone. The reduction in genuine recovery time means the hard sessions are never fully absorbed, and the aerobic base stops expanding. The intervention is to re-establish the distribution before adding more intensity.

PRACTICAL APPLICATION

DO THIS WEEK

Audit your intensity distribution for two weeks
Pull up your last 14 days in TrainingPeaks or Strava and colour every ride by zone. If more than 25% of time is spent in zones 3–4 on what should be easy days, slow those rides down first. The plateau often starts here.
Change your primary interval type for 6 weeks
If you've been doing threshold (2×20) work, shift to VO2max intervals (5×4 min at 110–120% FTP) for a 6-week block. Then return to threshold work — you'll likely find it has responded to the new ceiling.
Take one genuine recovery week and retest
Before assuming the plateau is structural, take a proper recovery week — cut volume by 40%, no intensity — and retest. A plateau test after fatigue is often not a plateau at all.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

MISTAKEAdding more interval volume when FTP stalls.
FIXVolume amplifies a good system. If the system is broken — wrong distribution, poor fuelling, missing recovery — more intervals make things worse. Fix the system before adding volume.
MISTAKERunning the same block structure for 16+ weeks.
FIXIntroduce a periodisation change every 8–10 weeks: swap training focus, adjust intensity balance, or include a regeneration block. Stale stimulus produces stale results.
MISTAKEExpecting linear FTP gains at every test.
FIXFTP gains are not linear. A plateau after several years of training is biologically normal. Progress may now come in smaller increments over longer timeframes — that is not failure, it is maturity.

FAQ

FREQUENTLY ASKED QUESTIONS

Is there a genetic ceiling on FTP?

Yes. VO2max and FTP are partly genetically determined. But most amateur cyclists are nowhere near their genetic ceiling — they are hitting a training or periodisation ceiling that is absolutely fixable with the right approach.

Does more volume break an FTP plateau?

Sometimes — if you are genuinely under-trained and have room to absorb more load. But often plateau-stuck riders are already at their sustainable volume, and what they need is better quality and distribution rather than more hours.

Can strength training break an FTP plateau?

For some riders, yes. Strength work improves neuromuscular efficiency and can add watts through better force application. The research suggests 6–8 weeks of concurrent strength and cycling can move FTP in plateau-stuck riders.

Should I try a different training method when FTP stalls?

If you have been doing primarily sweet-spot or threshold work, a block of polarised training (more zone 2, more VO2max, less middle) is often the circuit-breaker. The change in stimulus is the point, not one method being inherently superior.

How long should a training plateau last before I act?

If your FTP has not moved meaningfully across two consecutive 6–8 week test cycles (with proper prep), that is a plateau worth addressing. One flat test result is too little data to act on.
