I asked Chat GPT to write me a 12 week cycling plan to grow my FTP from 325 to 350. Here is what it came up with. What do you guys think?
Weeks 1-4: Base Building & FTP Intervals
Monday - Friday (2 hours each day):
Day 1: Sweet Spot Intervals**
Warm-up: 20 mins
Main Set: 3 x 12 mins at 88-94% FTP (285-305W), 5 mins easy spin between efforts
Cool-down: 10 mins
Day 2: Endurance Ride**
2 hours at 65-75% FTP (210-245W), steady pace, focus on smooth pedaling
Day 3: VO2 Max Intervals**
Warm-up: 20 mins
Main Set: 5 x 4 mins at 105-115% FTP (340-375W), 5 mins easy spin between efforts
Cool-down: 10 mins
Day 4: Recovery Ride**
1.5 hours at 55-65% FTP (180-210W), easy spin
Day 5: Threshold Intervals**
Warm-up: 20 mins
Main Set: 4 x 10 mins at 95-100% FTP (305-325W), 5 mins easy spin between efforts
Cool-down: 10 mins
Saturday**: Long Endurance Ride (4-5 hours)
Ride at 65-75% FTP (210-245W), include occasional climbs at threshold intensity (around 2-3 efforts at 10 mins at 95-100% FTP)
Sunday**: Rest or Recovery Ride (optional)
1 hour at 50-60% FTP if you feel like an easy spin
Weeks 5-8: Build Phase
Monday - Friday:
Day 1: Sweet Spot + Over/Unders**
Warm-up: 20 mins
Main Set: 3 x 15 mins at 88-94% FTP, alternating 1 min over FTP (105-110%), 1 min under (85-90%)
Cool-down: 10 mins
Day 2: Endurance Ride**
2 hours at 65-75% FTP
Day 3: VO2 Max + Sprint Work**
Warm-up: 20 mins
Main Set: 5 x 3 mins at 110-120% FTP (355-390W), 5 mins easy spin, then 4 x 30 sec all-out sprints with 4 mins rest
Cool-down: 10 mins
Day 4: Recovery Ride**
1.5 hours at 55-65% FTP
Day 5: Threshold Intervals**
Warm-up: 20 mins
Main Set: 5 x 8 mins at 100% FTP, 4 mins easy spin between efforts
Cool-down: 10 mins
Saturday: Long Endurance Ride (4-5 hours)
Same as previous weeks but aim to push a little harder on climbs or include more time at threshold (2-4 efforts)
Sunday: Rest or Recovery Ride**
Weeks 9-12: Peak Phase
Monday - Friday:
Day 1: FTP Test/Progression Ride**
Warm-up: 20 mins
FTP Test: 20-minute all-out effort to assess your progress
Cool-down: 15 mins If no test, substitute with a tempo ride at 90-95% FTP (290-310W) for 40-60 minutes
Day 2: Sweet Spot + Over/Unders**
Warm-up: 20 mins
Main Set: 3 x 20 mins at 88-94% FTP, alternating 2 mins over FTP, 2 mins under
Cool-down: 10 mins
Day 3: VO2 Max + Sprint Work**
Same as previous weeks but push the intensity higher on sprints (all-out)
Day 4: Recovery Ride**
1.5 hours at 55-65% FTP
Day 5: Threshold Intervals**
Warm-up: 20 mins
Main Set: 4 x 12 mins at 100% FTP, 5 mins rest
Cool-down: 10 mins
Saturday: Long Endurance Ride (4-5 hours)
Focus on endurance with 3-5 efforts at or near threshold
Doing 6h a week of high intensity work, in a 14-15h week, including VO2 max and threshold work, every week in the base phase… is maybe not a great idea.
The math doesn’t math. Example: the Day 1 workout in the base phase is stated to be 2 hours long, but the actual described workout is only 70min.
There’s no obvious progressive overload. Like it’s just “do the same workout every week for 4 weeks.” You’d have to calculate the TSS for each workout and see what’s happening with that over the course of the program.
There’s no allowance for FTP testing at any point during the program.
The VO2 workouts are prescribed by percentage of FTP.
The build phase has easier threshold workouts than base does.
Etc.
It’s like the early AI-generated pictures. On quick glance there’s nothing obviously weird about it. But the more you look at it the more you’re left scratching your head.
Edit: one more that has me puzzled is:
Day 3: VO2 Max + Sprint Work**
Same as previous weeks but push the intensity higher on sprints (all-out)
Just because you aren’t able doesn’t mean it won’t work. In college we did a program very similar (and that was for running), but also with a Saturday race and no rest day.
Not saying it is optimal, smart or anything I would want to do it now… but it does/would work.
Beyond some of the days not making any sense… not many people can handle 3 intensity days a week, and doing the same interval duration and intensity every week doesn’t help gain fitness. (Look up progressive overload.) Well it probably would work fine with noob gains, but not in people with any previous training background.
And for what it’s worth a well respected coach a physiologist once told me… “there’s three ways to improve: go further, go faster or do it again and it feels easier.”
I know many coaches that repeat workouts on micro cycles. Not saying that in this case, doing the same thing 4 weeks in a row is good (I think we can all agree here it’s not). That said we (me included) love exotic workouts. But in reality some good old traditional intervals is all you need.
Jack Daniels (author of Running Formula) has marathoners do marathon pace & threshold in the middle of their long runs. Ok, they are prescribed and not “arbitrary” (whatever that means) but it is a thing.
This is very good point. Asked same question with with somewhat overambitious goal (10% increase) and more specific details like training history, accustomed intensity distribution, current FTP etc. ChatGPT came up with similar plan as for OP but more tuned to what I already do.
Then asked additional question about how likely this goal is. Additional notes gave sensible advice: adjusting progression with halfway testing, taking recovery weeks, upping carbs intake. Although it still went little bit crazy with remark like “translates to an approximate 1% FTP increase per week. This is achievable, especially if you stay disciplined with recovery and nutrition.” based on my training history and having solid aerobic base. Sounds nice but it is usually other way around – more fit you are, harder additional gains come.
Anyway, added more details about goal event (24h bike ride, not race). Again, AI proposed sensible adjustments: long 4-6h Z2 back-to-back at weekends, with periodic sustained tempo efforts thrown in, keeping weekly VO2max workout but dropping threshold → sweetspot depending on feeling, tapering before event, finding food/drink mixes that are easy to stomach for long durations, etc.
Finally asked about reverse periodization. AI came up with revised plan, and listed benefits choosing this approach.
In summary, I’d say beginner wouldn’t go wrong with developed plan. Only problem is that I actually knew what I wanted to achieve in discussion (nudge AI to propose reverse periodization with 2 intense workouts per week). Basically, this would be my own advice to beginner myself having enough time at hand
Or differently put: to get good plan, you need to provide details. But to know to provide necessary details, you need to be already experienced enough so you don’t need AI to help you. And other way around is also true – if you ask as beginner without necessary details, you’ll get plan that improves you one way or another, just because you are beginner and any structure is better than no structure.
gonna agree with @Monkeyevil this is a dumb plan. there’s no progression to any of it, so essentially each “phase” is only a week you repeat. why vo2 and sprint? that’s also a dumb workout. 5x8 threshold, also dumb. and this is supposed to be a build phase and you’re not progressing TTE?
this is just a general purpose plan, which may or may not result in an ftp increase. if op has plateaued with ftp, they need a vo2 focused block with 2-3 vo2 workouts
To be very honest, a training plan isn’t too complicated.
It’s the commitment, availability, period of your life, etc that makes a plan effective.
A top-tier coach/training plan while you are having problems at work, studying, struggling financially, not sleeping and eating well, will bring you from X to X-1.
Now… you don’t have kids or they’re already “adults”. You’re well-established career-wise, consequently, financially-wise. You have 15hrs and really are committed. I’d say that an off-the-shelf TP plan will work for you.
