one on hand, riding bikes in prospect park at 6:30am everyday before work with the same 5 guys was religion to us. we laughed more doing loops and drinking coffee than I ever did at a club, and we did it daily.
on the other hand, we were pretty monastic everywhere else. we took our bikes to Spain once for a week, the same group. before they arrived I bought a 12-pack of beers. 9 of them were still in the fridge on our last day.
then other times, with a different group, we've been obliterated in the lower east side and I wouldn't trade those memories either.
the hard part about trends is they're new and changing, but talked about as if we were all supposed to be consistently living them for a while, and radically adherent to them. "the future of leisure is fitness" is an economic comment about where volume of hours/spend will be, but often confused for (and confuses people) about a lifestyle comment.
that is to say, people take hobbies extremely seriously now and anyone doing fitness for leisure (strictly) is de facto not being leisurely. there's no leisure in doing anything consistently, it's hard as hell to be consistent.
fitness is a trend with legs, but my economic comment is anyone building treadmill-based night clubs without also serving beer is you're going to get the monastic (i.e. wrong) crowd.
don't conflate volume of spend with consistency in lifestyle.
The future of leisure is fitness, running clubs are replacing night clubs for young people, alcohol consumption is falling, and oral GLP1s are going to melt literally billions of pounds of visceral and subcutaneous fat in the next decade in America.
The future is gonna be fit as hell (and a little bit boring)
