We breathe more than 20,000 times a day. Most of the time, we don’t give it much thought, since we do it automatically and all seems to go well… except when it doesn’t.

A hot humid day. One rider. One horse. Both are exercising at a moderate level. Who is more likely to overheat? It might surprise you to learn that your horse gets hotter much faster than you and is more susceptible to the negative effects of heat stress. Prof. Michael Lindinger, an animal and exercise physiologist at the University of Guelph, explains: “It only takes 17 minutes of moderate intensity exercise in hot, humid weather to raise a horse’s temperature to dangerous levels. That’s three to ten times faster than in humans. Horses feel the heat much worse than we do.”

I smiled, walking past the airport hat kiosk, en route to a judging adventure at an exhibition in Eastern Canada. I’d be wearing several hats and judging a kaleidoscope of classes at the show — equitation, road hack, reining, Western riding, working hunter, pleasure driving, driven dressage, conformation, showmanship, miniature horses… and more!

Purpose and performance of a foundational exercise - Certain exercises in a horse’s athletic development serve as a foundational skill set and a remedial tool later on. Leg-yield is exactly this kind of exercise. It offers valuable physiological benefits that improve a novice horse’s balance while also resolving specific impediments to an advanced horse’s quality of movement. It is the kind of tool that tunes up a number of shortcomings in how a horse is carrying himself.
