Heat Training Is a Free Performance Upgrade

Can training in summer heat actually make you faster in the fall? Miles and Amara break down the physiology of heat acclimation, including how plasma volume expansion, a measurable EPO spike, and improved sweat efficiency translate into real performance gains in cool conditions. You will learn what a practical two-week acclimation block looks like, why post-exercise sauna may be a smarter tool than outdoor suffering alone, and how sodium, not plain water, is the variable most athletes get wrong during heat training. Heat adaptation is not just a summer survival strategy, it is a year-round lever for anyone serious about building a more capable body.
