And that made me dread them less.
Really, push-ups aren't so bad once you get the hang of things. And as they became less painful (and I felt more powerful), I even came to enjoy them. I'll be honest: I don't plan to continue taking twice daily breaks, but now I feel comfortable doing a few sets of push-ups while stretching after an easy run.
By the end, my arms got noticeably stronger.
Maybe it was the combination of swimming and push-ups, but my arms felt firmer and looked a little more defined after my monthly challenge was over. My end goal was just to be able to do push-ups comfortably, and I achieved that. Were my biceps popping? LOL, no. But I could tell I was stronger, and that made me feel pretty darn good.
