I am ssssssssooooooooooo wimpy... I have had quite a bit of trouble with stuck stuff lately. I got mechanics gloves to help get a balance wheel off a stuck Singer 500 but I had to borrow my DH's hands to get it off - I think he had to take the rest of the day off and nurse his sore hands, arms & back... but the gloves worked.
Then I've had other smaller stuff I couldn't get any grip on so I found a bike inner-tube in the garage and cut a section out of it. I put it over a stuck thumb screw and used curved beak vice grips to get that off - I just don't like the idea of tearing anything up.
Then I had a couple stuck throat plate screws - I found a T shaped ratchet screwdriver with an extension and it takes the little screwdriver tips AND has a magnet - found at Harbor Freight. WOW it has leverage. I broke the screws loose with it and then used the little tips to get the screws out.
