I just did this for the first time and man am I going to be sore in the morning. It says it's a leg workout, but it definitely works your arms and core as well. I can't do burpees because of my ankle and knee injuries so I did a one minute wall sit. Here's to hoping that in six months I have my sexy legs back.

whoever came up with this idea is a genius! I have so many keys, and now I have a cheap way to not only make them look cool, but to be able to finally tell them apart without trying every single one on the doors.
