THE BARBELL PRESCRIPTION
AN EXERCISE MEDICINE TO FIGHT THE EFFECTS OF AGING.
As we grow older, it's harder to hang on to muscle and bone. Loss of this tissue increases frailty, insulin resistance, chronic pain, and susceptibility to injury and disease. We think that's unacceptable. A growing body of published research shows that strength training is the most important form of exercise for those in their 40s and beyond. When it comes to filling the prescription for strength, nothing comes close to barbells for safety, precise dosing, simplicity, and effectiveness across the entire range of fitness attributes.

We Train the Athlete of Aging
You Will Amaze Yourself
There's a difference between exercise and training. Exercise is something you do to get tired, sweaty, and sore today. Training is the use of a rational, long-term program to progressively increase performance, fitness, function, and body composition. Training is the difference between being merely active as you age and being an Athlete of Aging.
Strength Training for Older Adults
Start getting stronger now.
At Greysteel, we use a safe, proven program of barbell training to reverse the loss of muscle and drive rapid improvements in strength, power, endurance, mobility, function, and balance. Two days a week is all it takes to dramatically improve your fitness and health.

One-on-One Training
Get strong quickly, safely, simply.
At Greysteel, all training is semiprivate, and all trainees are coached directly by Dr. Jonathon Sullivan, a physician and Starting Strength Coach, at all times. Greysteel coaching--and results--are second to none.

THE BARBELL PRESCRIPTION
The Definitive Text on Fitness Over Forty
The Barbell Prescription: Strength Training for Life After 40 directly addresses the most pervasive problem faced by aging humans: the loss of physical strength and all its associated problems – the loss of muscle mass, bone mineral loss and osteoporosis, hip fractures (a terminal event for many older people), loss of balance and coordination, diabetes, heart disease related to a sedentary lifestyle, and the loss of independence.
