Just in time for #NewYear2020 resolutions, Sciency comedian Aaron Freeman talks with Boston University physicist Dr. Nick Gross about some of the #physics involved in walking and running.  Professor Nick makes the point that #bodybuilding and muscles are not what allow us to walk.  The force that propels us forward derives form the "frictional interaction" between the soles of our feet (shoes) and the floor we trod. And of course, there are jokes in the interview and a good time is had by all.
