To be fair I was well rested and since the heatwave is over I didn't have to fight the environment as much (although it rained and I was properly soaked and heavy).
Also I looked up how to properly move while running yesterday and I realized that I had to include my upper body more into my movements. Using my upper body more is still a thing I have to consciously decide to do but I'm really excited that it'll soon go into my muscle memory and I'll naturally move better.
Hard to say. During most of the summer I was focused on cycling and running was treated more like a side project. At the beginning of August I took a little break from being active and then I struggled due to heat. Right now I run a little over 8km per day and try to do so at least 5 times per week.
Earlier I mainly focused on running long distances but of course I wasn't very fast.
Now that I have more confidence in myself I do shorter runs but try to up the speed.
Is that just swinging your arms more or your torso as well? One video I watched recently said too much arm swing can also be counter productive so it's a fine line it seems.
I think I'd describe the movement more as shoulder based. Beforehand I feel like the center of movement lied more in my elbows but as I said it wasn't really a conscious act.
