Why are legs so much harder and more stressful to push to failure than arms/back/chest? Just started lifting a few weeks ago and holy fuck leg day kills me. My heart hits zone 4/5 doing legs and its almost more of a cardio struggle to try to push them to failure than it is a muscle one. Is it just the size of the muscles? Like the leg muscles are comparatively bigger so they're more stressful to work?

Take bicep curls, I can push those to failure in a few minutes without breaking a sweat, barely even hit zone 1 before I start to fail them. Meanwhile when doing bulgarian split squats (no gym, and i only have dumbbells and a bench for now) my heart is racing and I feel like I can't breathe long before I'm hitting muscular failure. I wonder if this will get better as I lose weight and gain muscle. Also they take longer to recover, like a day after working my biceps to failure they're no longer sore ready to go again. After pushing legs to failure I'm wobbly and sore for the next 3 to 4 days, which means my legs are almost perpetually sore right now as that period runs up into my next leg day workout, its like my legs are just getting to the point where they're not sore when, oh heavens look at the time, its leg day again.

I guess I can see why people skip leg days now and its such a meme that even a non-lifter fatass like me knows about it. I wonder if I should skip a leg day and let them fully recover before hitting them again, I haven't skipped a leg day yet but I understand the appeal now.
