The point is that regarding a photo taken at that point where the toe is just about to leave the ground, it is arbitrary to draw the line through that back leg which has pretty close to zero force on the ground.
it's not an "arbitrary line".....it would be a line exactly showing the kind of forward lean one should have at toe-off with their body mass relative to the ground and illustrating ankle flexion. When you start to plantar flex and are toeing off (think big toe power) there is absolutely more than "zero force on the ground" being applied by the push-off leg!
Here's a nice video. At 28 seconds, the stance leg is still a little bent and there is a little bit of ground reaction force. Take a look at 29 seconds which looks like the classic 'forward lean' photo with straight leg. Ground reaction force is zero.

..... this has been a lifelong quest of mine so i can confidently say that one of the major things that prevents most people from changing their posture, walking form, running form etc is in fact their ego: it's extremely uncomfortable to change one's posture because it makes us feel like everyone else notices the adjustment and surely thinks we look like a fool
Misleading? Horrible? Would you like to elaborate?
This guy has running technique & biomechanics as his job. He's been helping hundreds (maybe thousand) runners, both hobby-joggers to elite runners, to IMPROVEtheir individual technique! If you think he is looking for clickbait you are wrong Sage. Yes, he sometimes seems a little bit "loopy" in his way to describe things (especially when he's in the spotlight) but that's his image. He is a professional guy, highly competence helping people improve their running technique in a more efficient way.
In this video he simply says that "leaning forward from the ankles is BS" and then shows pictures of people running mid-flight (in the air) and says "where is the ankle lean?".... This was after showing pictures of people on toe-off with ankle flexion/forward lean. Watch the video. I think it's terribly misleading.
This is a classic piece of running technique advice: "The hands should only move forwards and backwards, they should not swing towards the centre of the body...

so ... beer?
whatever floats your boat, sure
i've found thc to be the best for me
only problem is my understanding of movement has become so advanced i've got nobody to talk to anymore
It sounds so logical that it must cost more energy to lift your feet and knees higher when running compared to not lifting your feet so high. For example, it...
From age two, U.S. swim club coaches perfect freestyle swimming form of swim club members, 50yd splash & dash before moving swimmers up in distance.
At an early age, 200m sprint development is the key to future success. Two-hundred meter sprint development should not be an add on at the end of practice.
Depending on height to weight ratio, inseam to height ratio, should an athlete sprint like Jesse Owens/Herschel Walker/Michael Johnson? Should an athlete sprint like Carl Lewis and many triple jumpers?
Did you notice yesterday which athlete, Josh Kerr or J Ingebrigtsen took sprint training seriously from their youth? Final 200m, J Kerr was applying maximum pounds of pressure to track surface. Re: J Ingebrigtsen's form. Up to 300m to go, run a comfortable manner as long as form is reasonably efficient. J Kerr had superior sprinting form yesterday.
