Portable Doorway Pull Up Handles (440lb) 26.55$

[Devil's_Advocate]

I have two pairs of these. They are quite good. I didn't realize their combined capacity is 440lb, I thought it was 220lb. This is on Ali Express.

They are a bit harder to use to do pull ups or chin ups than a regular doorway bar since they move around. You can't do neutral grip pull ups unless you grab them by the middle part which they don't recommend.
