I have covid and today's the last day to pick up my paxlovid from the pharmacy for it to have any effect, but my car has a flat tire. I've been trying for 3 days to get the lugnuts off, and I just can't get them unstuck. I'm using the shitty 8-inch tire iron that came with my car, and can't get enough leverage. I've tried jumping on it, I've tried beating it with a hammer, but they won't come off. And it's made even tougher by my diminished breathing and strength due to covid.
If you've got a jack for the car an old classic is to wedge the jack under the tire iron with thr car still on the ground then jack it up. It's slow but even shitty scissor jacks can generate tons of force.
Additionally I don't usually apply this to lug nuts but often a stuck bolt can be broken loose by starting it moving in the tightening direction then switching to loosening.
The car jack idea is great, been diying just about all my car stuff for decades and only now hearing it
