During an endurance challenge, the speaker maintained a fast walk pace with approximately 30 seconds of carrying weight followed by 30 seconds of rest or until breath was recovered.

“so like basically a fast walk you know you you want to make your legs and heart do as much of the work as possible because just holding that much weight in your hand becomes an issue you know um but really the reason why I'd say is even harder than running a marathon is when you're running a marathon like my heart rate's usually around 167 I have a really low heart rate what's your maximum heart rate I don't know what it would be now at that time though I I couldn't get it over 200 it was probably like 195 197 like I had a resting heart rate of 27 when I was at my fittest like it was I've always had a really low heart rate but it get super low now it's nowhere near that um but all that to say like usually the first 20 miles of a marathon or maybe the first 17 miles like feels pretty good you're conversational you're floating along like it's just fun you know you're just enjoying the ride and then of course like it gets really hard and you got to grit down and bear it whereas this was just like it was like I was doing interval training because I was right like I'm going like 30 second carries set it down take as minimal rest as possible what would a typical rest be when you did that 30 seconds on yeah like 30 seconds off kind of thing I would just go till I caught my breath and go again and uh and so it was like I'm breathing super hard when I set it down Catch My Breath just to where I'm breathing normally again and then go again”
