I do my lifting at home and don't have a suitable bench. I'm currently using two ordinary monoblock chairs as my "bench" and I don't think I'm doing my bench presses right because my arms are supported by the chairs.
So my question is: can the overhead press replace the bench press in the Stronglifts 5x5 or Starting Strength program?


either using dumbbells or a barbell. One issue with the floor press is that your arms do not go down far enough to work the bottom part of the press (off the chest) - but this may be a bit safer than trying to balance on chairs.
