Before you start exercising, your doctor may order a few crucial tests based on your age and medical history. If you are older than 40, overweight, or have a history of sickness or illness, testing including an EKG, a stress test, blood tests, and more are very important. Your doctor could have suggestions for the kinds of exercises you should undertake, and Steadfast Strength and Mobility is all about taking a “team” approach to your health. In order to make sure that you and your particular requirements are satisfied, your trainer will remain in touch with your doctor.
