This may work for some people, but not others. For me, nothing is as unpleasant as running. Back when I tried to forcd myself to do it as part of my gym routine, I was actively dreading it the moment I woke up, after a week or two. It took all my willpower every time to run another minute, another 100m, etc. No other exercise I tried is as unpleasant and demotivating to me.
