I've started running during my walks. Not going too hard at it. Probably more closer to a jog (a fantastic NZ invention) than anything else.
I do short runs, the first blitz I did was 450 metres long on the road. It was pretty flat so incline isn't to blame here. I started getting huffed out by the 400 metre mark, and I went back to walking at 450 metres because I was a nauseated faggot.
I was feeling pretty light headed and a bit dizzy. I was huffing and puffing trying to capture my breath. My legs weren't the limitation. It was the nauseous feeling that made me go back to walking.
I like running but this feeling sucks. Any tips?
This is gonna sound like a shitpost, but keep doing it and pushing yourself even when it hurts like hell. Your body isn't used to running, but if you keep going it will get stronger and adapt.
It also helps to not eat shit meals, drink a metric fuckton of water throughout the day (not all at once just before you run), and stretch before you go.
If you want a shitpost answer I'd recommend bionic legs or something
