I wonder, if there's a way to work out the arms similar to pull-up exercise, but without using pull-up bars?
Indoor exercises are convenient. I could just do push-ups in the living room. However, there's no bar in my flat and also cannot use pull-up bars due to the limit of the doors. I'm afraid only doing push-ups will make my arms unbalanced developed.
Is there a way to work out those "pull-up muscles"?
