Aww I'm sorry about your rib! I just wish I could do more ab stuff. I really need to work on cardio things because that is mostly what holds me back. Maybe that's normal though, not really being able to breath when doing crunches. I should move my coffee table (aka. old steamer trunk) and stick my feet under the couch for some real sit-ups instead. I know there are other things I can do (and Boyfriend knows some killer core workouts), but I like to put in my 5-10 min and be done.
We only have giant nail clippers (I lost my tiny ones booo), but that is good to know that they will work. I'll invest in a smaller pair soon and get Boyfriend's help in wrangling kitty. I am expert at towel-wrapping cats.
