Great gym with everything you need as a weight lifter. No frills, but the gym is super clean and is never that busy so you can get easily get a rack/equipment you need. 10/10 recommend if you're in the Sunnyside area.

I have been working out with Martha for about a month now and have truly never felt better! She makes each workout different and fun and always challenges you to do more than you thought you could. Even after just a month I am seeing great results and would highly recommend to everyone.

This gym is the best! Highly recommended! All of the trainers and staff are super nice and most of them are bilingual which is very inclusive. When I first came in to the boot camp and spin classes, they were very challenging but Maribelia, the owner of Masfit, encouraged me and was there to push me when I needed it. I was able to finish the whole workout and since then, I come to every class she offers whether it is morning or afternoon and have even gone to kickboxing classes. This gym is also very clean and I love coming!

I was looking for a hobby and my sister inlaw recommended me to get a gym membership and join the gym. I figured it wouldnt hurt to try. I got a membership and decided to go ahead and try classes with the trainer. It was the best decision I have ever made. I wasnt looking to loose weight (I was over weight) but to just gain more self confidence and feel good about myself (I didnt even know what I was really looking for). I started training about half a year ago with Rully and he has been an amazing trainer. I found that I didnt just go to the gym just to go to the gym but I learned to really enjoy and love every single step of the health and fitness process. Rully has made my gym journey super easy and enjoyable. Going to the gym is a routine that now I make sure I make time for. I went to the doctors for a physical and after I got my weight checked and when it was entered the computer the nurse had to llok at me twice. He said " wow, did you loose a lot of weight or did I note your weight wrong". My BMI dropped significantly that it was pretty shocking. Not only did I find a hobby that I enjoy but I lost about 30 pounds, I am lean, gained self confidence, healthier and most important of all I look good (I say that very proudly!) The trainers are great and super friendly! Thanks to MasFit I am now a healthier person.
