Hi, how is everyone?

I am new to weights and stuff, i just wondered how well negative pullups work, i have read a fair bit on them today and they seem to do the trick in actually helping to be able to build strength in doing normal pullups.

I struggle to do more than 4 pullups at the moment, so was thinking of doing as many negatives as i can when i do them, and then try to move up to normal pullups again in a few weeks to see if i have progressed, and if so, by how much.

Do they work, have they worked for anyone on here?

Thank you.
