New Heart Rate Formula for Women
According to a recent study, the standard heart rate formula, 220 – age, overestimates the maximum heart rate for women performing cardiovascular exercise. According to the New York Times report, The commonly used formula subtracts a person’s age from 220. But based on the data collected in the Chicago study, the right formula for calculating a woman’s maximum heart rate is a little more complicated: 206 minus 88 percent of a...
Obesity Panacea: Myth of the Fat Burning Zone
This is something I’ve written about myself, elsewhere, but researcher/blogger Travis Saunders sums it up pretty well – with a graph from a recent lecture, no less, which helps drives the point home.

Intensity vs. Time
Hot off the presses: another study confirming the benefits of high-intensity cardio vs. traditional, low-moderate intensity aerobics… The usual excuse of “lack of time” for not doing enough exercise is blown away by new research published in The Journal of Physiology. The study, from scientists at Canada’s McMaster University, adds to the growing evidence for the benefits of short term high-intensity interval...
Diana Nyad Blew It
