Greysteel Strength & Conditioning

GreySteel Strength and Conditioning is the first Starting Strength Affiliate Gym in the Detroit Metro Area. Owned and operated by Jonathon Sullivan MD, PhD, our practice is open to all ages, but specializes in increasing the strength, power, mobility and overall physical performance of those in their 40s, 50s, 60s, and beyond. We offer private and semi-private training only, and all trainees are personally coached on the platform by Dr. Sullivan at all times. Regardless of your current fitness level, we can design a training program for you that is safe, rational and effective. If you can still stand up out of a chair, lift your arms over your head, and pick a kitten up off the floor, WE CAN MAKE YOU STRONGER.
