Wolf- I often face the same dilemma. However I carry the (large size)Mesifta gemora as well as the (large size) Artscroll to work each day; I am fortunate to be able to do much of my learning at work. But there is no way I can carry any more volumes so I make sure I have completed a volume the night before.
I probably should have posted this on the “is it mutter to lift weights” thread as well:)
