Man I used to do 50 pullups a day in 8 sets and now that I'm running (even if it's not that much of a run) I can't pull off 25 😅 but I know that if I want to lose fat and get to the next level I got fo cardio. But I totally get your point, I end up wasted after the running session of the video. I just came back from today's session and I'm dying.
