Eh, this is a story written for and about the fitness industry, meaning gym professionals - personal trainers, group exercise instructors, and their administrators. (Never mind it's three months old.)

Other than the nod they give to running (and that only because unlike Spinning®, the treadmill manufacturers forgot to trademark their indoor workout), they don't talk about any participatory sports, only things that people can be taught to do in a gym.

Which are important supplements to sports.
