plod along
To move, progress, or develop at a slow but constant and deliberate pace. I've been plodding along with my thesis for the last few weeks and making some decent progress. My 95-year-old grandfather still makes a point of plodding along to the local shop each morning to catch up with neighbors and friends. As the lecture plodded along, I could feel my eyelids getting heavy.
plod along
to move along slowly but deliberately. I'm just plodding along, but I am getting the job done. The old man plodded along, hardly able to stand. The movie plodded along putting most of the audience to sleep.
