What is the most common position we humans adopt outside of sleeping now? If you said sitting, you would be right.
So what does sitting involve? Hip flexion and often in poorly designed chairs, even so called ergonomic chairs. So what do we not need more of when we eventually break up this sedentary behaviour with some physical activity? More hip flexion. Yet, this is what we get on a treadmill. How, you may ask? Well, the belt on the treadmill is moving you backwards so all the user need do is lift the leg up and fall forward without actually bringing their bodies forward to the same degree as needed in the real world. Restricted hip extension. Rinse and repeat. Hip flexion after hip flexion after hip flexion moment. Exactly what we don’t need as our hips get tighter and tighter and tighter already. And don’t even get me started on people holding on with their hands and leaning back while walking at an ‘incline’.
That’s why people like to walk on the treadmill. Because it’s easier and more sterilised than the real thing. Walk into any gym and you’ll see this. You may also see this in people running outside if they’re so used to sitting that they’ve already lost their hip extension.
So what is the solution then? You guessed it, normal walking in real life. But what is different in normal walking then? Well, there is such a thing as ground reaction force. We push into the ground and the ground pushes back and this propels us forward when we push back and down. We activate our posterior chain, our hamstrings, calves and glutes. Especially if we go barefoot. Hip extension or the opposite of hip flexion, as we drive our hips forward. This is not required with the treadmill as there is already a force moving us backward so all we have to do is counter it by bringing our knees up. You’ll find you can’t just bring your knee up in the real world as there is no force driving you forward. You need to push off the ground. Hip extension.
And when most people simply raise their legs up they tend to overstride and rely too much on the quads to lift the knee. The femur gets jammed into the pelvis and the hip muscles shorten. Tighter and tighter hips. Just like with sitting. There are ways to walk naturally that actually open the hips but that’s too much for this post.
So what are the alternatives then? Walking outside is the obvious one. Barefoot, grass, in the sun and fresh air. Number one with a star. This is what we are designed to do.
But what else if you must get some ‘cardio’, it’s dark or wet outside and you insist on some variety? Well, the bikes are out as they involve more sitting and they are not natural movements. Elliptical trainer is again unnatural so that leaves the rower but again more sitting and most people don’t do that properly and so are likely to get into shoulder issues. Why do people who sit all day want to sit down to exercise? Counterintuitive isn’t it? Especially if they first have to sit in the car to drive there…
So if I don’t propose machines then what?
Here are my top two suggestions and guess what, they both involve hip extension. You probably won’t be surprised by kettlebell swings given my background but the other one would be jumping rope. Very hard to perform either of these activities for decent time and reps without some solid hip extension. And you can’t tell me they aren’t cardio and a lot of hard work. The rope may be a very good entry into the swing as many people will try to do a combination squat/front raise to get the bell up, but it’s very hard to jump rope well without extension at the hips, knees and maintaining a decent posture. The rope can teach you the top position of the kettlebell swing. The kettlebell swing also teaches force generation and absorption. A great exercise.
Then there are always burpees. Hip extension, check. Force absorption, check. Plus some healthy power generation. Notice a theme yet?
Shorter duration but more intense cardio. Great in today’s world when we are all pressed for time. You don’t get fitter by covering the same ground in more time but by doing it in shorter and shorter times! The third option would be sprints but yes, you have to learn to walk before you can run. Sprints are fantastic but only once you have your mobility restored.
But if this is all too intense for you? My favourite restorative cardio would have to be crawling. Try doing that for 10 minutes or more and tell me which muscles you didn’t use and which joints you didn’t open up. It will ground and restore you.
