Do something every 15 minutes

Last week, my sister's trainer who is overseeing our competition, challenged us to set a timer for 15 minutes when we are sitting watching tv, facebooking, blogging about losing weight... and every 15 minutes get up and do something like jumping jacks. I did that for exactly 15 minutes. I was way too into House of Cards. Today I am having a stay at home day and am going to get this house clean. I am going to try this challenge. Every 15 minutes I will do something burpees, push-ups, sit ups, lunges, jump rope...
