Charlie Francis was famous for the High/Low model developed for his track athletes. But that doesn't mean the concepts only apply to track athletes. This approach when effectively applied to athletes of any sport will produce tremendous results. The key principle of the system is to separate your training into high and low intensity days, with a minimum of 48 hours between High intensity days. This allows for the body to perform at its peak on a more consistent basis by providing the necessary recovery between high intensity training sessions.
How are High/Low days defined or structured?
High intensity days will include any activity that produces high levels of metabolic or nervous system stress. Examples would be explosive sprints/jumps/throws, explosive strength exercises, and high-intensity interval training to name a few. On those days, overall volume of exercise is kept to a moderate level. Low intensity days are designed to keep workout intensity at a moderate level while allowing your body a chance to recover fully. The low days are a great time to include technique work, sport specific drills, and aerobic capacity development drills such as tempo runs.
