You're not new to this. You train 8 to 12 hours a week, you've got a power meter, you did the structured plan. Year one your FTP went from 240 to 280 and you thought, right, this is how it works. Then it stopped. Eighteen months later you're still staring at the same number, doing the same 2x20s, reading the same arguments on Reddit about whether sweet spot is dead, and quietly wondering if that's just your ceiling now.
It almost certainly isn't. The reason your FTP stalled is rarely a missing magic session. It's usually that the system around the sessions is leaking — and that's fixable.
I've spent the last few years putting the question of how amateurs actually raise their FTP to the people who coach the best riders in the world: Professor Stephen Seiler, the physiologist behind the polarised model; Dan Lorang, head of performance at Red Bull–Bora-Hansgrohe; John Wakefield at Science to Sport; Joe Friel, who wrote the book most coaches learned from. This is what they actually say works, stripped of the noise.
What FTP is, and why it's the number that matters
Functional Threshold Power is, roughly, the highest power you can hold for about an hour before the wheels come off. More precisely it tracks your lactate threshold — the intensity above which lactate floods in faster than your body clears it. Below threshold you can ride for hours. A few watts above it and the clock starts ticking.
It matters because almost everything hangs off it. Your training zones are percentages of it. Your climbing speed is mostly FTP divided by weight. Following a surge, bridging to a break, not getting dropped on the third climb — all downstream of threshold. Raise FTP and the whole performance picture moves with it. (To see where your number places you by age and category, we built the 2026 age-group benchmarks for that.)
Now the part you came for.
The five proven methods to raise FTP
There's no single best session. There's a toolbox, and which tool you reach for depends on whether you're trying to lift the ceiling or lift the floor underneath it. These five are the ones with the evidence and the coaching mileage behind them.
1. Polarised base — the easy riding that makes the hard work land
This is the one amateurs skip, and it's the one that holds everyone back. Seiler's research is blunt: the best endurance athletes spend around 80% of their training easy — easy, conversational, the pace where a recreational rider could sit on your wheel and chat. The other 20% is properly hard.
The amateur mistake is riding the middle. As Dan Lorang put it to me bluntly, most age-groupers ride 50% too hard on the days they think they're going easy, and not hard enough on the days meant to hurt — the grey-zone trap Seiler's 80/20 model is built to break. That grey zone — Zone 3, tempo — builds almost nothing while leaving you too tired to nail the real sessions.
The base isn't filler. Easy Zone 2 riding builds mitochondrial density, capillary networks and fat oxidation — the aerobic base your threshold sits on. A bigger base means a higher ceiling for everything above it. Do it: the easy 3–4 hour weekend ride is the most important session in the week. Protect it. Don't let it drift into tempo because your mates half-wheel you.
2. Sweet spot blocks — the most time-efficient watts
Sweet spot is 88–94% of FTP: just below threshold, where you get a big aerobic stimulus for a fraction of the recovery cost of all-out threshold work. For the time-crunched rider — and that's most of you — it's the highest return per hour on the bike.
Do it: start with 2x20 minutes at 90%, building to 3x15 or 3x20 over a block. Two of these a week in a focused 4–6 week block reliably moves FTP, especially if you've been neglecting structured work. The trap is living there permanently — sweet spot is a fantastic builder and a poor finisher. Use it in blocks, not forever. (The full case is in our complete sweet spot guide and the sweet spot vs threshold vs polarised comparison.)
3. Threshold intervals — training the exact thing you're measuring
If FTP is your hour power, threshold work is the most specific way to raise it. These are sustained efforts at 95–105% of FTP that teach your body to produce and clear lactate at exactly the intensity that defines your number.
Do it: the classics earn their reputation. 2x20 at 95–100% with 5 minutes easy between. 3x15 at 100–105% when you want it sharper. 4x10 with short recovery to hold quality. When I asked about dose on the threshold episode, the principle was simple: enough total time at intensity to drive adaptation (start around 40 minutes of work across the session), progressed week to week, not so much that you can't recover for the next one.
4. Over-unders — teaching your body to buffer
This is the session that wins races, and it's the one most amateurs never program. Over-unders alternate just above threshold and just below it without stopping: 2 minutes at 105%, then 2 minutes at 90%, repeated. The "over" floods you with lactate; the "under" forces you to clear it while still working hard. You're training the buffering and clearing systems directly.
Do it: 3 sets of (3 minutes over at 105% / 3 minutes under at 88–90%), 5 minutes easy between sets. It's brutal and it's specific — this is what it feels like to hold the front group when the pace keeps surging. Add it once you've got a threshold base; don't make it your first interval session.
5. VO2max work — lifting the ceiling
Your FTP can't keep climbing if the ceiling above it doesn't move. VO2max is that ceiling, and threshold typically sits around 75–80% of it. Spend long enough only doing threshold and you'll grind to a halt because there's no headroom left. VO2max intervals — 3 to 5 minutes at 106–120% of FTP — push the roof up so threshold has somewhere to go.
Do it: the 4x4 is the most research-validated protocol going — 4 minutes hard (the top sustainable effort you can repeat four times), 4 minutes easy, four times through. Full detail in our VO2max intervals guide. These are the sessions that produced the FTP jump in the episode on adding 30 watts after one workout — but they're costly, so one a week is plenty and two is the absolute maximum in a short block.
The order matters. Coming off unstructured riding, build base and threshold first, then add VO2max to lift the ceiling, then sharpen with over-unders. Throwing VO2max at a rider with no aerobic base is like revving an engine with no oil.
How to test FTP properly
You can't manage what you measure badly. Two tests dominate, and the right answer is "pick one and be religious about the conditions," but here's the honest comparison.
The 20-minute test. Warm up properly, then ride 20 minutes as hard as you can sustain evenly. Your FTP is 95% of that average. This is the closest practical proxy to true one-hour power and it rewards muscular endurance — the thing FTP is supposed to capture. The downsides: it hurts, and it punishes bad pacing. Go out too hard in the first five minutes and you'll blow up and under-test. It also needs a hard 5-minute effort beforehand to deplete your anaerobic contribution, which is why a lot of "my FTP dropped" stories are really "I skipped the opener."
The ramp test. Power steps up (commonly +20W per minute) until you can't hold the next step. FTP is estimated at around 75% of your best one-minute power. It's shorter, far easier to pace, and very repeatable — which is why platforms love it. But it systematically over-rates riders with a big anaerobic punch and under-rates true diesels, because the result leans on a one-minute number rather than sustained work.
Which is better? For tracking progress, the ramp test wins on repeatability and the fact you'll actually do it. For a number that reflects your real road and racing threshold, the 20-minute test is closer to the truth. The cardinal sin is mixing them — never celebrate a "gain" that's actually a protocol change. Test the same way, same trainer or loop, rested, every 6–8 weeks. Not every fortnight — that just disrupts training and tells you nothing.
Realistic timelines, by where you're starting
This is where people get demoralised, because the internet promises everyone 30 watts. The truth depends entirely on your training age.
- First year of structured training: 20–40% over the year is on the table, often 15–25W in a single 6–8 week block. This is the biggest gain you'll ever get. Don't waste it chasing VO2max you can't recover from — build the base and bank the easy wins.
- Two to three years in: 10–20% a year, slowing to 5–10W per block. Structure starts to matter here; unstructured riding plateaus fast.
- Experienced, near your ceiling: 2–5% a year, and sometimes a flat line for months followed by a 10W step-change in a single block. Both are normal. At this level, gains come as much from weight management and discipline-specific work as from raw watts.
Two honest caveats. These assume consistency across the whole year — three good months and nine ragged ones won't do it. And progress is lumpy, not linear: the rider who stays consistent for six months beats the one who trains like a hero for three weeks and burns out, every time.
FTP for masters cyclists
Here's the news the over-40s never get told: the age ceiling is far higher than you've been led to believe. The widely-quoted 10%-per-decade decline in aerobic capacity comes from studies of mostly sedentary people. In cyclists who keep training with real intensity, the longitudinal data lands closer to 5% per decade. Half the drop. And most of what masters riders experience as "getting old" is actually lost training consistency — fewer hours, less intensity, more life — dressed up as physiology.
When I had Joe Friel on about going faster after 40, his point was that masters athletes who keep intensity in the program hold their numbers for years longer than the ones who quietly turn every ride into a Zone 2 plod because "that's what you do when you're older." Cut the intensity and you accelerate the decline you were trying to avoid.
What changes is recovery capacity. You can still hit the same peaks — you just can't hit them three days running the way you could at 25. So the training adapts: the same five methods above, but with more easy days around the hard ones, often a 2:1 work-to-recovery week rhythm instead of 3:1, and non-negotiable sleep. Push the ceiling with the same VO2max and threshold work; protect it with more recovery. Masters riders setting all-time FTP PRs in their mid-50s is common, not freakish.
The FTP plateau, and how to break it
A plateau is information, not a verdict. It's telling you that whatever you're doing has stopped providing a new stimulus. Four things cause nearly all of them:
- Monotony. Same session, same intensity, every week. The body adapts and then stops. Rotate the five methods — if every hard day is a 2x20, that's your problem.
- The grey zone. Easy rides creep up into tempo, so you're never truly recovered for the hard days and never truly building base on the easy ones. The fix is counterintuitive: go easier on easy days.
- Buried fatigue. You've actually built the fitness, but accumulated tiredness is masking it. This is the one a rest week fixes overnight (more below).
- Under-fuelling. The stimulus never lands because you're doing your intervals on empty.
The single most common fix isn't a harder session — it's a recovery week plus softer easy days, which lets the fitness you've already built finally surface. If you want the full diagnostic, we wrote why your FTP is stuck and the five real causes and a dedicated plateau breakthrough guide.
Nutrition's role: fuelled beats under-fuelled, every time
You cannot out-train an empty tank, and under-fuelled intervals are a waste of a session. If you go into a VO2max set low on carbohydrate, you produce lower power, you generate a smaller training stimulus, and you recover worse for the next session — you've paid the cost and skipped the benefit.
The practical rule: fuel the work. For any hard session over an hour, take in 60–90g of carbohydrate per hour so you're hitting the intervals at full power. Eat before you ride. Stop training fasted for your quality days — save fasted easy riding, if you do it at all, for genuine low-intensity work. And mind the longer game: adequate daily protein (around 1.6–2.2g per kg of bodyweight) is what lets your muscles actually rebuild from the sessions, with protein before bed a small edge worth taking. The full picture is in our in-ride nutrition guide.
Recovery: why rest weeks actually raise your numbers
This is the bit that breaks people's brains. Your FTP doesn't go up during the hard week. It goes up after it, when you back off. Training is the stimulus; recovery is when the body actually builds the watts. Skip the recovery and you accumulate fatigue that sits on top of your real fitness and hides it — your form is your fitness minus your fatigue, and a buried rider tests low despite being fit underneath.
Take a recovery week every 3–4 weeks (every 2–3 for masters riders). Drop volume by 40–50%, keep a couple of short, sharp efforts so you don't go flat, sleep more, eat enough. The classic experience: rider grinds through a hard block, takes the rest week reluctantly, tests at the end and finds 10–15 watts they swear weren't there before. They were there. The fatigue was hiding them. Our recovery week guide and the rest week structure lay out exactly what to do.
The common mistakes that stall FTP progress
Most of these you'll recognise. Most are fixable this week.
- Easy days too hard. The number one error. If your recovery rides live in Zone 3, every hard session suffers. Easy means easy enough that it feels like cheating.
- Two hard days back to back. Hard sessions need 48–72 hours of easy riding around them. Stack them and you get the cost without the adaptation.
- One session forever. Endless 2x20s. Your body adapted to that months ago. Vary the stimulus.
- Under-fuelling the work. Covered above, and worth repeating because it's so common.
- No recovery weeks. Training through fatigue, then blaming your "ceiling" for numbers that are just buried.
- Testing too often. Every two weeks disrupts the rhythm and tells you nothing. Every 6–8 weeks, same protocol.
- Chasing watts while ignoring weight. At the top end, W/kg moves faster through sensible body composition than through raw power — see our age-group benchmarks for what realistic looks like.
None of this is mysterious. The riders who break through aren't doing secret sessions — they're doing the right sessions, fuelled, recovered, and varied, for long enough to work.
