“Patrick Zeiher, owner of CrossFit Indian Trail, notes that one reason CrossFit is so beneficial for all ages is that the physical needs of a person vary by degree — not by kind. ‘We can literally have a 60-year-old athlete doing a similar variation of a workout as a 25-year-old competitive athlete,’ he says. ‘Their needs don't vary by kind; in other words, they both need to be able to squat to a toilet, pick something up off the floor, or get themselves off the floor.’”
