Some more juice for me that might also apply to you:
It is free. Even if it's not free, it's cost-effective for good barbell training. We're not talking about one that is preferred by the Instagram community though
I suck. It's part of a personal push
Helps build a routine, the need to go at the same time; while getting fresh air, the need to go out/commute
Helps waste less time since there is nothing else to do but exercise. Doing one thing at a time rocks
Helps focus on the core application of the proper set, not the phenotype
It's busy/crowded and the best time is after the morning rush (i.e. 10-11 am), which helps reap the benefits the whole day. Normally, I would do it after work/day which would have a smaller window to leverage benefits
Helps learn the right way to exercise. While not strong enough, it's prone to develop wrong/damaging patterns and when it's carved in the brain, it will stick there and hard to mutate it. On the other hand, somebody who knows their shit in the gym can teach the right form from the beginning, way easier
It has a high signal-to-noise ratio to learn about discounts, trends, generations, expectations, etc.
If something goes wrong (i.e. pushing too hard), there are people around to help or vice versa to do a good deed
A tremendous number of options are available for different body parts. Courageous to swim?
There are a lot of beautiful and motivating people around. Environment matters
The grit of people around is more than average and some are exceptional so are successful people in their domains
The diversity of people around is also surprisingly mind-blowing, the luck surface of serendipity is wide
If team members know each other well, the routine is in place and the training program isn't very tough, then it might be a great standup; casual & friendly
