Are humans better at pushing or pulling?
For a majority of the processes, pushing is preferred. A meta-analysis of the research on pushing/pulling shows that, as humans, we are capable of safely generating more force when pushing, rather than pulling. This is due to the postures experienced while pushing and muscle recruitment.
