Why My FTP Dropped And I Blame The Couch
My FTP dropped, and I blame the couch. It sat there quietly while I chose a blanket, a snack and one more episode over the noble pursuit of producing watts. The couch did not even look guilty. It simply absorbed my training plans, my motivation and, possibly, a small portion of my aerobic capacity.
Functional threshold power is supposed to offer a tidy snapshot of cycling fitness: the highest power a rider can sustain for roughly an hour, or the number estimated through a shorter test. It gives training zones a useful anchor and allows riders to track progress without relying entirely on whether the legs feel “pretty good, mate” on a particular morning.
The trouble is that FTP is not a permanent identity document. It changes with fatigue, heat, illness, stress, training load, sleep and the accuracy of the test itself. A disappointing number may signal lost fitness, or it may simply reveal that the test was performed after a hard week, a poor night’s sleep and a breakfast that consisted of half a banana found in the car.
The Couch Is Often An Accomplice
Blaming the lounge furniture is emotionally satisfying, but the real issue is usually reduced training consistency. A week or two of missed intervals will not erase years of endurance, yet a long stretch of easy spinning, cancelled sessions and passive recovery can lower the power a rider can sustain. Fitness adapts to the demands placed on it. When those demands become mostly reaching for the remote, the body adjusts with impressive efficiency.
This is especially easy to notice through an Australian winter. In Melbourne, a cold and wet morning can make the wind trainer seem like a punishment designed by a committee. In Canberra, frosty roads and dark starts can push riders indoors, while riders in Brisbane may face humidity that turns a tempo session into a personal sauna. A few skipped workouts can become a pattern before anyone admits that the “recovery week” has entered its fourth consecutive fortnight.
The couch may still deserve some blame, particularly if it has become the centre of an evening routine. Long hours sitting can leave the hips stiff and the legs feeling flat, even when overall fatigue is low. That stiffness does not directly prove that FTP has fallen, but it can make a hard effort feel harder and reduce the quality of the training that follows.
A Lower Number Does Not Always Mean Lost Fitness
FTP testing is sensitive to conditions. A ramp test rewards riders who tolerate increasing discomfort and can produce sharp anaerobic efforts. A twenty-minute test rewards pacing, confidence and the ability to suffer at a steady level. A long outdoor effort may be affected by traffic lights, corners, wind and the need to avoid becoming a mobile road hazard. Each method measures something useful, but none delivers a perfect reading of an athlete’s entire condition.
Power meters can add another layer of confusion. Batteries, calibration, temperature changes, dual-sided discrepancies and drivetrain settings may influence the result. Even a reliable device can show different numbers from an indoor trainer if the power measurement locations do not match. Comparing an outdoor test on a crank-based meter with an indoor test on a smart trainer may be like comparing two bathroom scales after one has been moved onto carpet.
The test itself can also be badly timed. A rider who completes a tough group ride on Sunday, works a full week, sleeps poorly and tests on Tuesday has not discovered their true potential. They have measured their ability to suffer while carrying accumulated fatigue. That number can be useful, but it should be interpreted as current readiness rather than a permanent verdict on cycling performance.
A strong test requires repeatable conditions: similar equipment, a familiar warm-up, a sensible pacing strategy and enough recovery beforehand. If the result is unexpectedly low, repeat the test after several easier days rather than immediately rewriting every training zone and announcing retirement from the bunch.
Heat, Fuel And Recovery Change The Equation
Australian conditions can make power output feel oddly negotiable. A summer ride around Adelaide’s hills, a humid session near the Gold Coast or a long exposed stretch outside Perth can raise cardiovascular strain before the legs reach their intended workload. Indoor training is not automatically easier, either. A garage with one small fan can become a sweatbox where the heart rate climbs while the power quietly disappears.
Heat affects performance through increased cardiovascular demand and fluid loss. Riders may interpret a lower power file as declining fitness when the main problem is insufficient cooling. A large fan, regular drinking and appropriate electrolyte intake can make an indoor threshold session much more representative. On hot days, moving the workout to early morning is often smarter than trying to conquer the afternoon like a hero in a poorly ventilated shed.
Fuel matters just as much. Threshold work relies heavily on carbohydrate, and under-fuelling can make the final intervals collapse. A breakfast of black coffee and optimism is not a performance nutrition plan. Eating enough carbohydrate before a demanding session, then replacing energy during longer rides, helps protect training quality and reduces the chance that a low test reflects an empty tank.
Recovery is the quieter part of the equation. Sleep, rest days and manageable work stress influence how well the body absorbs training. Australian cyclists often stack work, family commitments and long commutes around dawn rides, then wonder why their legs produce the power of a supermarket trolley with one crooked wheel. Fitness improves during recovery, not during the heroic act of repeatedly refusing to recover.
Read The Training File Before Judging The Rider
A single FTP result is less informative than the trend around it. Look at recent training volume, intensity, heart rate, perceived exertion and the quality of completed intervals. If endurance rides remain comfortable, heart rate behaves normally and only one test is poor, the result may be an outlier. If easy rides feel difficult, resting heart rate is elevated and several workouts have deteriorated, a broader fatigue problem becomes more likely.
Training platforms can make this review easier, although no graph can replace common sense. Compare similar routes and durations rather than treating every ride as a direct contest. Wind, gradient, road surface and traffic change outdoor power demands. A fast ride along Melbourne’s Beach Road with a tailwind may create a flattering average, while a blustery return can make a fit rider look like they have been carrying a piano.
Race results and hard group rides also provide context. A rider who has posted a weak test but still handles the final climbs in a Saturday bunch may not have lost as much fitness as the number suggests. Conversely, a rider who cannot stay with a familiar wheel and struggles through routine intervals should pay attention. The broader record is often clearer than a single laboratory-style attempt in the pain cave. Reviewing race reports can also remind riders that performance is shaped by pacing, tactics and conditions, not only by a headline wattage figure.
Use trends across several weeks. Note the duration of steady efforts, repeatability of intervals and power at a familiar heart rate. If endurance power is stable but short, intense efforts are down, fatigue or poor freshness may be the issue. If every zone feels reduced for a month, consider detraining, illness, inadequate nutrition or a training plan that has become too demanding to sustain.
Rebuild The Number Without Worshipping It
The best response to a disappointing FTP is usually calm consistency. Reduce the temptation to compensate with punishment sessions, especially if the decline followed illness or a heavy block. A week of sensible aerobic riding, one or two controlled intensity sessions and genuine easy days may restore performance more effectively than an angry series of maximal efforts.
Resetting training zones temporarily can be sensible if the new number is supported by several signs. It prevents endurance rides from turning into accidental threshold sessions and keeps structured intervals achievable. The adjustment should be treated as a practical setting, not an admission that the cyclist has fallen from greatness to garden furniture.
A useful plan includes different kinds of work. Easy endurance builds volume without adding excessive stress. Sweet spot and threshold intervals develop sustained power when the rider is ready for them. Shorter high-intensity efforts support top-end capacity, but they should not dominate the week. Strength training, mobility and regular movement away from the desk can help maintain the physical foundations that indoor training alone may miss.
Habits That Put Power Back In The Legs
- Test under repeatable conditions, using the same device, warm-up and general time of day where possible.
- Take at least one easier day before an FTP assessment, and avoid testing during illness or heavy fatigue.
- Eat a carbohydrate-rich meal or snack before demanding sessions rather than relying on coffee and determination.
- Improve cooling indoors with a strong fan, light clothing and regular fluids, especially during Australian summer.
- Track sleep, stress, heart rate and perceived effort alongside watts to identify patterns behind a poor result.
- Replace missed training gradually with consistent rides instead of attempting to “make up” every lost session.
- Find a supportive local bunch or event through LetsRide.co so training has a social purpose beyond chasing a number.
FTP is valuable because it gives structure, not because it deserves worship. It can set zones, guide interval targets and show long-term progress, but it cannot measure confidence, bike handling, tactical awareness or the ability to keep riding when the weather turns foul. A slightly lower number does not cancel the fitness built across months of steady work.
The couch can remain part of the training ecosystem. It is excellent for recovery, stretching, reviewing ride files and watching professional racing with the serious concentration of a directeur sportif. The key is making it a tool rather than a permanent training partner. If it receives every evening and the bike receives whatever time remains, the power curve may continue heading south.
Recheck the number after a consistent block of training, adequate fuelling and proper recovery. Use the result to guide the next phase, then get outside and apply it to real riding. Join a local group, enter an event, or organise a winter loop with riders who make showing up more enjoyable. The fastest route back from a flat test is rarely self-punishment; it is a repeatable routine that gets you off the couch and turning the pedals again.
