30 Day Plank Challenge

Hi everyone! I've been reading a lot about the 30 day plank challenge, and I've seen some pretty impressive before and after abs pictures. Apparently it helps a lot with core strength, so great for shouldermounts etc. I've decided to give it a go, and if anybody else wants to join I'll post my 'before' pictures up that I just took and we can do it together! I'm using a free app called '30DAYS' which has loads of different challenges. You do an initial test of how long you can hold a plank (I managed 34 seconds)and it works out a programme for you based on that - I've got it on medium at the moment but may have to drop down to easy at some point :P so let me know if you fancy it!
