I'm going to completely disagree. Having been on that side that felt it was the only "practical approach," I was fooling myself because I didn't want to take the plunge and put in the mental effort required to do 14-16hrs a week. I rationalized that I could get by with 5-9hrs a week. That HIIT was just as good if not even scientifically better. But the truth of the matter was and is that there is no substitute for hard work. But that's just it, it's "hard" work and we all know the mind breaks long before the body. This is especially true after you spend 8-9hrs at the office.

Here's the crux: People basically want to come home from work and have the training equivalent of a microwave dinner. Push a few buttons on the smart trainer and off you go...

So personally, I would reword your sentence "not because that is the better approach but because for many people it is the mental easier approach."
