My friend was telling me about this app called tribe sports (www.tribesports.com) they also have phone apps. I work out nearly every day and do yoga classes twice a week. So this was a nice little add on they have thousands of challenges and you choose the ones you want to try and you have friends encouraging you on your challenge. Like the first one I did was 10 push ups a day for 7 days. They have all kinds and it's free hope you guys enjoy!
