Definitely.
I train UFC to this day, and it definitely improves my game. Now, most of the girls you run into in UFC class are fugly, so I wouldn't recommend actually trying to meet girls that way.
But what I usually do is, when I go to my local Planet Fitness to weight train, I try to get in a few rounds of shadowboxing in between sets. Punches, kicks, the whole 9. I typically get one or two hotties approach me each day and ask me what I'm doing. I tell em I'm training for an upcoming match, then engage in some flirty banter and sometimes take them to the Zumba class room and show them a few grappling positions. The girls get extremely turned on at this point, a couple even soaked their panties (I can tell visually or through olfactory confirmation). It's only a matter of time before I take them home and drill them till they "tap".
The kicker? I don't actually compete, just train for fun. But they're none the wiser.
