I love Kickboxing is not really a gym, which is why it won't show up on Google maps for gyms - I don't think New Self Image will either. They're places to take classes and for personal training. Jackson Heights doesn't seem to have much at all in the way of gyms, nor any outdoor tracks to run in, so places where you take classes like this seem to be the only option for fitness. Honestly, it's been incredibly frustrating for me. I would love to have a normal, clean, decent, regular gym around here where I can go at my convenience, but they don't exist. So I'm desperately trying to find what will work, even though it's more expensive to be forced to work out this way. And I know if I have to get on a subway just to work out, it won't happen. I'd walk 20 minutes if I could find something decent. So far I've found:
New Self Image: zumba and TRX classes, plus nutrition and personal training sessions. Will try it this week and report back.
I Love Kickboxing: http://www.ilovekickboxingjacksonheights.com/ 85 and Roosevelt: great kickboxing classes but gets very crowded, class times tend to be inconvenient if you have plans at night, no day classes
MiMi's Yoga - haven't had great luck with finding pilates instructors I like there (the one I did like, left)
Dance Studio 43: zumba on Saturdays - I really like this class but it's only one day a week

I've also heard there is a gym called UFC or something but I've heard staff are rude, it's small, and it's one of those you get what you pay for type places. Still, I may check it out just to see for myself, if they have a 2wk pass or something. edit- Just saw your review on it here:
http://www.jacksonheightslife.com/community/index.php?topic=83.135, I'll check it out anyway but I have a feeling I won't love it based on the description. And the other one - Executive Fitness sounds worse.
If any potential entrepreneurs are reading this - a real nice gym would be a great business venture here
