Fitness 19 - West Mifflin Jennifer Jusko: Ive been going to Fitness 19 West Mifflin gym for I think, about 7 years. I do the silver sneakers classes and machines. I LOVE ❤️ it. The instructors are fantastic. The people going there are so friendly. I have made many friends going there. They have all the equipment you could want, great classes and will answer questions and help you with anything you ask. You HAVE to keep moving, no matter what your age. I live with severe pain, but it definitely is better if I go than if I sit at home. If not for this gym, I wouldnt be able to keep going. Thats the truth. Try it..it grows on you, and you will meet the absolute nicest people, too.
