Most of you already know by now that I’m not a fan of “traditional” cardio.
Step aerobics classes have ruined enough knees, Achilles tendons, and hips.
Ellipticals don’t allow you enough hip flexion to avoid developing hips like a crowbar.
Most people don’t need to sit on their fat a**es on bikes, either because most people, well, they sit on their fat a**es enough as it is.
In short, as I’ve noted in the past in my discussions of The Law of Repetitive Motion Part 1 and Part 2 , take a small amplitude of motion and repeat it thousands of times and you’re going to wind up with some issues sooner than later. And, to take it a step further, you’re going to get efficient at this motion - and over the course of time, burn fewer calories (especially if you’re doing steady-state cardio and not interval work).
And, if you need one more example, here was a little fun I had with an impromptu conditioning session on Sunday afternoon at Cressey Performance: Alternating Lateral Lunge Walk with Keg paired with Inchworms.
I’d already done some cable woodchops, t-push-ups, face pulls, slideboard, easy sprinting progressions, and medicine ball throws in a circuit format that day (pair up two exercises with low resistance and rotate back and forth without stopping for three minutes). It’s not rocket science because we aren’t building rockets; people just need to move more.
