Absolutely gorgeous gym and locker room. Doug & Brian spec'd the best equipment and set up the gym perfectly. Unstoppable Strong is a West Chester gem.
Wow…what a gym! I used to workout at Mitch’s Gym in West Chester before it closed and have since followed Doug and Brian to this facility. Everytime I arrive, I am always welcomed by them along with a super clean gym environment. They go above and beyond to provide exceptional personal training sessions, have unique equipment, and plenty of recovery supplements and drinks to help you achieve your workouts goals! This is the place to go for a more private gym experience without the crowds and for some killer workouts!
I enjoy everything about Unstoppable Strong. The equipment is state of the art and Brian and Doug are the best. I really believe these sessions keep me as healthy as possible ! Fun being around the other clients, too. I highly recommend this gym.
They broke the mold with these amazing trainers. I wish everyone would search out Doug and Brian to find out what I have always known... They care about you and your health, they truly will help you become as the name implies... Unstoppable!!!
I followed Doug & Brian from Mitch's Gym and am very happy with that decision. Their studio is state of the art including all brand new, top quality equipment. Doug & Brian are both knowledgeable trainers and create programs tailored to fit every client. It's a warm, welcoming environment so I also feel comfortable working out on days I'm not having a personal training session.
My recovery from back surgery has been smooth with no setbacks working with Doug. He’s so knowledgeable on the right way to build back safely and fully. No matter your age and fitness goals (young athletes or grandparents wanting to maintain mobility—and everything in between), this is THE place to achieve them. The gym is gorgeous and both Doug & Brian are friendly and funny!
Brian and Doug are amazing trainers who meet you where you are at, challenge you to improve and do it in a way that is sustainable and also fun! Unstoppable Strong is an immaculate gym. You will not find a cleaner, more top of the line gym anywhere in the area.
I grew tired of large commercial gyms where you are just another $ to them. This gym has become a HOME filled with great trainers who care about everyone walking in and out. Brian MUSCLEman always makes me smile and pushes me to be my best. Would give this place six stars if they let me.
Great ultra-clean facility with new equipment. Awesome trainers. Can’t recommend highly enough.
