The government currently recommends three categories of movement—cardio, strength training, and stretching—which can be likened to the macronutrient groups carbohydrates, fat, and protein. Without a better prescription for what to eat/how to move, the moves we consume to meet our recommended daily allowance (RDA) become mostly junk. And, without co

Over time, I began piecing together a mathematical formula, taking the optimal heart rates in athletes who had previously been assessed as a guide. Instead of 220 minus the chronological age multiplied by some percentage, I used 180 minus a person’s chronological age, which is then adjusted to reflect their physiological age as indicated by fitness

When my colleague Dr. Aaron Baggish attached accelerometers (tiny devices, like Fitbits, that measure steps per day) to more than twenty Tarahumara men, he discovered they walked on average ten miles a day. In other words, the training that enables them to run back-to-back marathons is the physical work that is part and parcel of their everyday lif

Trade floppy fins for bum knees, collapsed arches, eroded hips, tight hamstrings, leaky pelvic floors, collapsed ankles, you name it—and consider our load profile. Walking on a treadmill an hour a day creates an entirely different load profile than walking over the ground for an hour. Wearing shoes to walk that hour creates a different load profile

Recent research also shows that runners wishing to improve their speed should spend at least 80 per cent of their time at low intensity, so beneficial is it to heart, muscle, skeletal and neurological health.
