Aw, thanks badgercurls! I find that if I'm not consistent, I just won't do it at all, so doing it every day just works best for me.
Wednesday AM: abs + 35mins elliptical. I've moved up the resistance to an interval program that alternates between levels 5-7 of resistance. I've just started this this past weekend and it is definitely harder than my previous 2-4 level intervals, but it feels good that I can "move up" to a harder program.
