Fitness, like anything else, is partial to trends, and at the moment, exercise is portrayed in extremes. “You've got to do HIIT training. You've got to run marathons. You've got to lift heavy.” The actual truth is much less snappy and attention-grabbing: fitness should be balanced and well-rounded. Slow and intentional is better than intense and sloppy.
There’s one functional exercise which is particularly good at challenging us in the ways we often forget, and most of us have never heard of it: the Turkish get-up.
