    The confounding variable in this situation is the disparity between the days of the week on which individuals performed physical exercise to improve their mood.

    Perhaps, individuals generally have a lower and more supressed mood on Mondays versus Thursdays causing the results to be skewed as they failed to account for the confounding variable of different dates.
