About Custom Fitness
The business is owned by Keith Grainger, who began lifting for injury recovery and has coached clients in fat loss, strength, muscle gain, rehab and general health. Jack Ryan also trains clients and says he has coached hundreds of people in person and online over five years.
Under remote coaching, the coach sets the training programme and nutrition habits, and the client trains in their own gym, at home or outdoors on their own schedule. Clients log sessions in an app and have a weekly email check-in; the coach is available seven days a week for questions.
