Our 5,000 square foot facility on Woodland Ave in Springfield PA gives us more than enough room to play with all kinds of fitness toys. Our workouts may feature barbells, dumbbells, assault bikes, kettle bells, jump rope, Concept 2 rowers, boxes for jumping, jump rope, battle rope, or weighted sleds. Though sometimes gravity is all we need.

Whether you’ve been working out all of your life or brand new, the trainers here will work with you to make sure you’re doing everything safely and effectively. They’re also some of the nicest, most encouraging people I’ve ever met. I felt instantly comfortable with this gym when I started. In the six months that I’ve been a member, I’ve progressed so much physically and mentally. I am stronger, healthier, and happier. I recommend this gym to anyone who is looking for real change and progress in their life. -Dani
Fantastic gym, the guys there have changed my strength, endurance, and mental toughness. I’m glad that I chose to join. - Gabe
I needed an atmosphere that I could bring my baby with me at times. It was the best decision I made. I am currently the strongest I have ever been and pushed to limits that I never thought was possible. The coaches are so friendly and always go the extra mile to help with all of your fitness needs. They even entertained my little guy at times so I could finish a class! Not only are the coaches great, but so are the members and I have formed new friendships. Best gym in Delco!! - Diana
