no because you have to be moving your arms for work yo be done.
WORK in terms of Physics is only done when there is motion of an Object. So even though you may tire while standing still wearing a Pack, NO WORK is being performed on the Pack itself (in terms of Physics). Once you start walking, then there is work being done MOVING the pack forward, as well as UP and DOWN! To find the total work done on the Pack, you would have to use Vector representation of the Forces and the Motion to solve the entire System's Work Performed.

"The nick of time" means being able to get something done just before the dead line. It can also mean carrying out an action, which could have had bad results if it had not been done at that precise moment.
