The Old School New Body program is a diet and exercise plan created by Steve and Becky Holman for those aged 35 and up. It addresses the fact that aging accelerates after 40 without proper nutrition and exercise. The program consists of three phases - the first burns fat, the second builds muscle and provides toning, and the final phase focuses solely on building muscle. Regularly following the program can help burn fat, build muscle, tone the body, and even slow the aging process to make one look up to 10 years younger.
