tonight i did an interval program on the elliptical for 45 min. it was tough but i made it. it wasnt as tough at last night but i worked harder if that makes sense at all. i felt it in my outer thighs and butt which was kinda cool. i ran 5.55 miles which is more than last night even with the added resistance. woo! tomorrow is my day off from cardio but i still have strength training. 🙂
