The 2016 Reebok CrossFit Games were a grueling five-day, 15-event test to find the fittest man and woman on Earth.

The CrossFit Games challenge competitors to perform intense physical tasks, but the hardest part is sometimes mental. Athletes often learn the details of the events only minutes before they begin, and everyone handles the pressure differently.

So here's a portrait of yoga in the 21st Century: this ancient discipline, created thousands of years ago to enhance the meditative experience (the asanas or poses commonly used in hatha yoga were in fact designed to enable meditators to sit quietly, calmly and comfortably for hours on end), is now "a total body blast," with users urged to "get hard core" and "feel the groove," all so "your torso will look buff." At least that's how Ellen Barrett, the relentlessly sunny instructor featured in Crunch Yoga's Super SlimDown: Pilates Yoga Blend, sees it. But while that approach may sound pretty frightening to traditionalists, this can't in fairness be viewed as a typical yoga video; nor does Barrett, who commingles power yoga moves and what she describes as "core-conditioning power pilates," make any claims that it is. Many of the poses-including Warrior II, extended right angle, cobra, locust, and others-will certainly be familiar to yogis.
