The National Personal Training Institute is private for-profit school with multiple locations in the United States that provide students with the education and training to become certified personal trainers. It is a 500 or 600 hour-long program that can be completed within 4, 6 or 12 months. The course covers roughly 100 hours of exercise program design, 100 hours of nutrition, 100 hours of anatomy and physiology, and 200 hours of practical experience. A part of each day is spent in a classroom setting learning the academic information and the remainder of each day is spent in a gym setting learning the practical aspects of personal training and actually working out.
