Good going man. I understand about the time efficient thing but the way I look at it is, you're not wasting $/health/time in a bar like you said and you already gain something from just going to the class by staying fit. If you pickup or befriend a gal, that's a bonus right there.Up until the pandemic started, I had been going to fitness classes on and off for nearly a decade. I would do this more when I needed to find new women. I mostly went to high intensity interval style classes and boxing/kickboxing. Most of the time, I went to classes at my regular gym, but I occasionally went to secondary facilities to put myself in front of a brand new audience. I tried yoga a few times, it definitely was not my thing.
I'd recommend fitness classes over bars. The ratios are much better.
I've been fit during the entire time I've gone to classes. Almost no guys, fit or unfit, tried to pick up women at classes.
I was able to get dates as a result of class attendance. It's not the most time efficient thing. You're going to a 45-60 minute class just for the purpose of talking to women 5 minutes before class and 5 minutes after class. Some women aren't all that social before or after class, even with each other. One would think women would want to talk to each other to make friends in a place like that. Anyway, it's a narrow window to make things happen, so you've really got to be to the point in that venue.
