It’s hard to lift without equipment - nothing around the house concentrates that amount of weight into something liftable. Pull up bars mostly work the back muscles but don’t provide enough isolation to work the biceps. I have however seen a video recommending bicep curls where your arms pull against a towel folded across your foot, which pushes in the other direction. By locking the elbows, isolation is achieved and your leg which has larger muscles than your arms provides the counterweight. It’s not ideal but it’s better than nothing.
