When I turned 29 last month I put together a 30 Before 30 list of things I wanted to accomplish over the next year. One category was a list of fitness challenges that included a 5-minute plank. I do a 15-minute core workout everyday so last night I thought I might give this one a try and see if I couldn’t knock it out on my first try. Mission accomplished. I held steady – well, slightly shaky by the end – for all five minutes! Here’s to checking the first thing off my list!
