For me the big deal was going 5 times a week with no possibility to skip during the week. My brain seed it as an extension of work, so it just goes.

When I skip, I put together two session next time (e.g. cardio + weight lifting). 3 years in and the only days I really skipped are those I am parked in bed due to fever.

But, I don't like it at all. I feel great afterwards, exhausted but great. I am now used to it, but I really appreciate going the smallest amount of time for maximum gain, so I do 2 times a week HIIT (30 minutes) and 3 times just 1 hour of weight lifting. Big results, minimum effort.
