No surprises here maybe. The Primal Blueprint prescription for general fitness, good health and optimal gene expression is:
– 2-5 hours low level intensity activity per week. In the aerobic zone 55-75% maximum heart rate.
– 2 strength training sessions per week of less than 30 minutes each. Intense enough that you cannot continue longer than 30 minutes maximum.
– An all out sprint session every 7-10 days when motivation and energy levels are high.
