Being someone with a back injury, it's important for me to keep my back flat and in a neutral position.
It's all a matter of physiological differences and needs, hence my disagreement for classifying one posture as better than the other.
I think you are correct the guy in the front is most likely not that good of a bike rider.
I saved that photo and added the blue and red lines because I thought it was a great comparison of weight and balance over the crank. And even more a good comparison of what causes hand and arm strain and takes away body weight from the legs that you can use to push against while cranking. If you look at Lance’s body and the line that shows how even his mass is over the crank. Between that and core strength his arms are not shooting straight down the forks, hardly holding any weight.
For me if you want to know how to sit you need to know how to stand. Put your heals against a wall and try and touch your toes without falling forward. Now move out from the wall and allow your butt to move back as you lean forward. That athletic position is what you need to feel on the bike. Do the same experiment now with a chair in front to catch your weight with your hands. You will see Machka means by sitting lightly. When you have heals to wall you will find how much weight the hands are holding as you move your sit point back yo will feel hand pressure go and the weight move between your butt and your legs. Every time you push down you will be taking weight off your seat point when your arms are holding the weight every push on the crank will put weight on the arms.
The “guy” in the front IMHO is in a much better position for power and comfort.
