Not sure if this was directed at me, but…
I do indoor workouts during the summer when I can because of the time efficiency. I can usually get a pretty good workout in outdoors but by the time I travel to the roads where I can do the intervals (or where the group ride starts) and back I’ve wasted a lot of time.
I find for me the choice is often between sleep and exercise - I can’t sacrifice my time at work and if I’m getting home at 6 or 630 the only way to get a workout in and still cool down enough to be asleep at a reasonable hour is to immediately hop on the trainer.
I much prefer being outside, and do that when possible, but it’s a rare day that I’m not out the door at 7 AM and home around 6 PM - I have to make the best of the time available
