What should i consider when beginning an exercise program?

Exercise starting: First, an evaluation by a healthcare professional, either a trainer, or your doctor. At 38, you could have some undiagnosed medical conditions. High blood pressure, arthritis, elevated cholesterol, back problems...which all could affect an exercise program. Second, start slow. Low impact. Short amount of time. Many get frustration by expecting results too fast. Try to do too much, too quickly.
