This is a video of a man (who I assume is a personal trainer) clearly itching for some cardio, but, with no electric treadmill and presumably a blizzard outside, makes his own makeshift treadmill by adding a little powdered soap and water to a tile floor. Just make sure you have a solid grip on something when you're running or you are going to bite that soapy tile with your pearly whites. So, yeah, between this for cardio and bodyweight exercises for strength training, you really have no excuse not to start a basic workout program besides being tired and lazy, which, for the record are valid excuses and I don't care what my doctor says. You know what I told him? I told him I'll start running when he starts seeing me at my scheduled appointment time. I felt pretty good about that one, but not so deep down I knew my future health problems aren't going to be prevented with sass alone.
Keep going for the whole video, and please, make sure there's a friend or family member nearby to drive you to the hospital if you try this.
Thanks to DT, who agrees it is going to be significantly harder to work out with a broken hip after slipping and falling doing this.
