40 sit ups a day for 40 days ?
Has anyone stuck with this challenge that I made a long time ago ?? I have ! I've been doing it everyday since.. which is way past 40 days. I've seen great results ! If you haven't stuck with this.. I'd definitely suggest it ! Soooo, who's with me?!
Hi. Are you still doing this routine ? I have a tendency to stress my neck&back too much doing sit ups. Can you give any recommendations or an exercise alternative ? Thanks
