Whether or not a trainer works for someone doesn't really matter. If it does, great. If it doesn't, great, too.

What's efficient for you may not be effective for someone else. At the end of the day, effectiveness is what matters to me, not efficiency. If spending 15 extra minutes riding outside helps me finish a workout that I wouldn't finish indoors, then the indoors wasn't as effective. That's the case for me.

I doubt my idea of an effective sprint workout is the same as yours, and it doesn't need to be because my workout demands are vastly different than yours.

At the end of the day, it is what it is. If the trainer helps you accomplish workouts, awesome. I'll hop off the trainer after a 20 minute warmup to go do hill repeats in the rain if that's what necessary to get my workout in, because that's what works for me and always has.
