Day 19 of the #30days60secCoreChallenge

Fun day at the crowded gym, doing planks with medicine ball, to create some instability. My abs are still hurting from yesterday's ab rollers. Ab roller exercises are really painful, and take a while to recover from.

Here's how we do it: 
1. Execute a core exercise movement for 60 sec, 30 days. 
2. Video, post online, hashtag #30days60secCoreChallenge and#livethechange
3. Tag 5 friends to get them into action too. 
4. Explain why we do it. (transform ourselves and one person at a time). °
