Tone: Friendly, constructive criticism:
I personally don’t dig the idea, and would never answer. I’d really like an option to not even see this survey; it would really throw me off my game starting a WO.
I sort of get where the question is coming from; if you’re already run down, this will help explain why you rated a 8.1 difficulty VO2 ‘Very Hard’, when you ranked a lesser workout Easy the previous week.
I can easily see how the Adaptive Training algorithm could be adjusted to alter the user’s rank either more, or less, from the post workout survey response, given their motivation level going in.
7.5 user does 8.1 workout, Stoked + Very Hard = Small or no bump up, Tired + Very Hard = larger bump up, etc.
But:
1 – We’ve got some overlap w post workout survey. If I do an 8.1 today and call it Very Hard, but I did an 8.1 last week and called it Easy, we know what’s up. I’m not magically weaker. [And if we flip this, I’m also not magically stronger in 3 – 7 days.]
Furthermore, once I call it Very Hard, we get an opportunity to input Sleep, Nutrition, Stress, etc. So we’re already doing the motivation survey, in a slightly different form, are we not?
I mean… Bottom Line: If I’m tired from lack of sleep, and unlikely to perform well / not as well as expected on my current growth trendline, there is already a catch net for this data. Correct?
2 – Too Wishy-Washy, and not enough data. You guys nailed it on the post workout survey by providing very clear cut definitions for each response. Users know exactly how to answer.
How “motivated” am I ? Like… to succeed overall, and want to push myself to keep advancing IRL & in TR? How energetic I currently feel? If I feel like I have all the time in the world to enjoy this, or if I’m really cramming this between dinner and a medical appointment, so unfortunately not fully able to enjoy?
3 – Trying to measure too much, that possibly isn’t measurable, or relevant. If I slept poorly, or a customer made a bad decision at work, but I’m able to shake it off, get on the bike, and kick some butt, that’s all that matters. Perhaps in the minority, but I spend all day really looking forward to my workouts, they’re often the best part of my day! And also psyching myself up to knock them out of the park! Extra few hundred cals at lunch, spicy music on the drive home, no negative thoughts, etc. I don’t want to jump on the bike to have someone ask me to think about “How motivated am I?” …. Oh, right. Slept poorly….true…. : / I just want to jump on and rip! : )
5 - If I’m really too tired to do my AT recommended WO [extremely rare], it’s up to me to adjust it down a bit, and I want to directly be in control of that. I don’t want the system to step it down for me if I’m not feeling at 10/10 maxxxed-out super-power level one million. [So if forced to respond, I would literally always answer 5/5, 3/3, etc.]
If you do proceed, I’d strongly recommend making it a 2 or 3 option input only, instead of 5. It will force a significantly different response, and more significant and actionable data.

instead of 
= Good to go
= Maybe ready, but uncertain
= Not great
In that sense, the lights / color may not work well vs the face / emoji that is potentially more “obvious”.
