I lost 110 lbs, started running world marathons in my 40s, and now I test everything so you don't have to. This is Mark Stache — health, food, and fitness content for normal people who want real results without blowing up their life. Every week: food science, 30-day experiments, fitness in your 40s, and honest takes on whatever the internet is currently freaking out about. No extremism. No supplements I don't use. No advice I haven't tested on myself first. New videos every week. Subscribe if you're curious. For collaborations contact: MarkStache@solaromgmt.com
