By trade, Ruban is a personal trainer at GoodLife Fitness in Kitchener, Ontario, so he knows his way around the stationary running machine.

In the video, Ruban performs an incredible routine to Michael Jackson's "The Way You Make Me Feel" during the celebration of the gym's 36th anniversary.
In one week, the video accrued over 420,000 views on Facebook alone, and for good reason: It's amazing.
