Eli "fetsh" Heiman
Hi, I'm Eli (he/him mostly), based in Ramat Gan, Israel. I am a father of two daughters. I love to explore new things, — such as exercise physiology, Haskell, or Hasidic philosophy, — to help people, to run, to swim, and to endure in general.
Apparently, I mostly write about running, though that may change. Here are three random things I've written (you can find the rest on the posts page):
I’ve been working at a surgical hospital for half a year now. In this post, I explain what a hospital orderly actually does, what my shifts are like, and why I enjoy working here.
Trying to understand and visualize how much sweat a foot produces during one run.
A detailed exploration of how the body produces and manages energy while running. The article explains ATP production systems, the role of glycogen and fats, the meaning of lactate thresholds, and why aerobic development forms the foundation of endurance performance.
Since my main passion is running, I couldn’t resist including some of my stats. I try to run 80–90 km per week, and sometimes aim for 100 km (though it usually ends with some kind of injury).
These are recent competitions I've taken part in, as well as upcoming ones I plan to participate in. I’d love to do more, but lately there has been too much war around me, which makes it difficult.
And this is a heatmap of my runs over the last two years.
