What Is FTP and Why Does It Matter?
FTP stands for Functional Threshold Power. Think of it like your cycling “cruise control” limit—the max effort you can hold for about 60 minutes.
It’s not your sprint. It’s not your top gear. But it tells you how strong you are over time.
If you’re training for time trials, races, or long rides, improving your FTP means you can ride faster, longer, and recover quicker. You’ll feel less cooked after climbs and hold higher speeds on the flats.
Here’s the thing about functional threshold power gains: they build slowly, like stacking bricks. But over time, they create a solid foundation for everything else. Endurance, power, and even sprinting.
You can measure FTP in different ways:
- 20-minute test: Multiply average power by 0.95
- Ramp test (Zwift, TrainerRoad): Structured increases until failure
- 60-minute test: Brutal, but the truest FTP
One of my athletes once hit a 20-minute PR on a windy day. She thought it was a fluke, until we calculated her new FTP. It was a real breakthrough and it gave her confidence that her training was working.
So if you’ve ever asked, “Why hasn’t my FTP gone up?” remember: measuring the right way is step one.

How Much Can You Actually Increase Your FTP?
Quads and Hamstrings: The Pedal Power Pair
Here’s the truth no one tells you: your FTP gains aren’t linear.
In your first year of focused training, you might see a 15–25% jump. But after that? Gains slow down.
That’s normal.
Let’s break it down:
- New cyclists can often improve 30–50 watts in 3–6 months
- Intermediate riders might see 10–20 watt bumps in 6–12 weeks
- Advanced cyclists often work months for a 5–10 watt gain
So when you ask, how much can I increase my FTP, the answer is: it depends on where you’re starting.
During my own first structured block, I went from 218W to 252W over 12 weeks. That’s nearly a 16% increase and I felt like a machine on hills I used to crawl up.
But after that? Gains came in tiny steps. 3 watts here. 5 watts there. I had to shift my focus from chasing numbers to loving the process.
And that’s key.
FTP doesn’t improve just because you want it to. It improves when training, rest, fueling, and mental focus all line up.
One of the most realistic FTP gains in 6 weeks is around 5–10 watts. If your training plan is dialed in.
The takeaway?
Be patient. Track your progress over months, not days. And celebrate the little wins, because they add up.
What’s a Realistic FTP Increase per Month?
Everyone wants to know, “How fast can I get faster?”
On average, most cyclists can expect an average FTP increase per month of:
- New riders: 5–15 watts/month
- Intermediate riders: 2–5 watts/month
- Advanced riders: 1–3 watts/month (if that)
But this only happens with smart training. Junk miles and overtraining won’t help. In fact, they’ll hold you back.
Imagine FTP like building muscle. You don’t bench press once and add 20 pounds to the bar the next week. Same with power on the bike.
A client of mine hit a plateau after three months of random Zwift rides. We switched to a structured block( sweet spot intervals, rest days, and fueling better) and he gained 12 watts in 6 weeks. His comment? “I actually ride less, but I’m stronger.”
That’s why having a clear structure matters.
Some riders are surprised they don’t see gains despite hard work. That’s where recovery, stress, and nutrition often come in. They can quietly block your body’s ability to adapt.
Here’s an insider tip: track more than FTP. Look at how your legs feel on climbs, how fast you recover, and how steady you hold power. These clues often show progress before the number goes up.
Bottom line: monthly increases are possible, but they require quality over quantity.
How Long Does It Take to Improve FTP?
Let’s say you train 3–5 times per week. You eat well, sleep decently, and follow a plan. How long until you see results?
Most riders can expect noticeable gains in 4–8 weeks.
If you’re consistent, your body will adapt. That means better oxygen use, stronger legs, and improved endurance. But if you’re wondering, how long does it take to improve FTP, here’s the timeline:
- Weeks 1–3: You may feel stronger, but FTP likely won’t change
- Weeks 4–6: Your power starts to shift. Riding at threshold feels easier
- Weeks 6–8+: Time to test again. You may see a 5–15 watt improvement
Just don’t test too often.
Testing every 2 weeks can backfire. It adds stress and distracts from real training. Aim for once every 6–8 weeks, unless you’ve made big changes in training volume or intensity.
One of my newer riders was eager to test every 3 weeks. After two flat results, she felt discouraged. But I reminded her. Gains come from adaptation, not testing. She waited, trained smart, and nailed a 14-watt jump six weeks later.
Stick with the process. Ride the waves. FTP growth is coming.
What Are the Best Workouts to Improve FTP
Now we’re getting into the fun stuff.
If you want to know the best workouts to improve FTP, think steady, sustained efforts. Not all-out sprints.
Here are your go-to zones:
- Sweet Spot Training (88–94% FTP): Builds strength without crushing fatigue
- Threshold Intervals (95–100% FTP): Teaches your body to work hard for longer
- Over-Unders (95–105% FTP): Simulates racing and builds lactate tolerance
Example workouts:
- 3x15min @ 90% FTP with 5min rest
- 4x8min @ 100% FTP with 4min rest
- 5x5min @ 105% FTP with 5min rest
If you’re using a FTP training plan for beginners, start with 2–3 sessions per week. Keep it simple, but focused. Too many intense days = burnout.
And remember: easy rides matter. They flush the legs, keep you consistent, and help avoid injury.
One of the biggest mistakes I see? Riders jumping into threshold work too soon. Without base fitness or aerobic strength, it’s like running a marathon after one 5K.

Can You Increase FTP Without Overtraining?
Absolutely. In fact, it’s the only way to build long-term power.
Trying to push every ride leads to fatigue, stalled progress, and even sickness. The key is balance.
Here’s how to increase FTP without overtraining:
- Limit hard sessions to 2–3 per week
- Take at least 1 full rest day weekly
- Fuel your workouts. Before, during, and after
- Track sleep and mood as recovery markers
- Drop intensity if motivation crashes or legs feel dead
Recovery isn’t lazy, it’s where you actually get stronger.
One rider I worked with was plateauing after 10 weeks of high-intensity intervals. I asked how much sleep he was getting: “Maybe 5 hours on workdays.” That explained everything.
We backed off for 10 days. Focused on sleep. Added easy spins. When he tested again, his FTP jumped 9 watts. His takeaway? “Less is sometimes more.”
Listen to your body. Rest when needed. Train smart, not just hard.

How Should You Test FTP at Home?
Testing at home isn’t just convenient. It’s accurate, if done right.
There are a few ways to do FTP testing for cyclists at home:
- 20-minute test: Warm up, ride all-out for 20 minutes, multiply avg. power by 0.95
- Ramp test (Zwift, TrainerRoad): Gradually increases power until failure
- 60-minute steady ride: Most accurate, but mentally tough
Tips for better results:
- Test when fresh. Not after a hard training block
- Eat a light carb-based meal 2 hours before
- Use a fan and consistent environment
- Pace evenly. Don’t surge early
If you’re nervous, don’t worry. Everyone feels the butterflies before an FTP test. That’s normal. The key is pacing and belief.
My personal favorite? The ramp test. It removes pacing guesswork and gives a solid baseline (great for beginners and experienced riders alike).
Whatever test you use, stick to the same one each time. That way, you’re comparing apples to apples.
And after you test? Celebrate. Even if the number didn’t move much, the act of testing itself builds mental toughness. That’s a win.

FTP Progress Timeline: What to Expect Over Time
Let’s take the guesswork out of it. Here’s a breakdown of what most cyclists can expect when training consistently, eating well, and recovering properly.
Use this table as a general guide, not a strict rule. Everyone progresses at their own pace based on training age, genetics, and life stress.

| Rider Type | Training Age | Expected FTP Gain (6 Weeks) | Best Training Focus |
|---|---|---|---|
| Beginner | 0–6 months | +10 to +25 watts Rapid gains due to new stimulus and structured riding. |
Sweet Spot & Threshold Intervals Build foundational endurance and leg strength. |
| Intermediate | 6 months–2 years | +5 to +15 watts Moderate gains from progressive overload and aerobic focus. |
Over-Unders & VO2 Max Improve lactate clearance and high-end aerobic power. |
| Advanced | 2+ years | +3 to +8 watts Marginal gains that require precise planning and recovery. |
Race-Specific & Lactate Tolerance Sharpen intensity and fatigue resistance. |
These numbers are based on athletes following structured plans 3–5 times per week with proper fueling, sleep, and stress management. If you’re not seeing these gains, consider adjusting your intensity, adding recovery time, or switching to a new stimulus like block periodization.
Also remember, FTP isn’t everything. Improvements in your repeatability, recovery, and ability to hold high percentages of FTP are just as valuable, especially in road racing, triathlon, or mountain biking.
Even a 5-watt increase can make the difference between hanging on or getting dropped in a group ride. So track your progress, stay consistent, and celebrate those small wins (they stack up faster than you think).
Final Thoughts: Ride Your Own Progress
Your FTP is one number. However, it’s not the only number that matters.
Power comes in many forms. Mental strength. Recovery speed. Confidence on the bike. These things grow, even when FTP doesn’t.
So next time you wonder, how much can I increase my FTP, remember: It’s not just about the watts.
It’s about showing up. Trusting the process. Enjoying the ride.
With the right plan, recovery, and mindset, you’ll see gains (real ones). Some big. Some small. All of them earned.
