Categorically can't do pull ups or bicep curls. I need something really hard to challenge my biceps, they are my weakest point and the hardest thing to train without equipment.

    You can largely follow some advice you gave someone else for this problem. But as it stands, there's not really a question in your post, so it's going to be closed as "Unclear what you're asking" unless you focus in on a particular problem, and ask a clear, answerable question about it.
