Monday workout

The past two Mondays I have done my Nike Anytime Anywhere workout through my Ipod.  I've been doubling the cardio section... I end up running about 3 miles and doing lots of lunges, squats, squat thrusts, planks, plyometrics, and other moves that make me really sore strong.  It's funny, I first downloaded it when I made a commitment to get in shape after my second child was born.  I remember how I couldn't finish it or walk afterwards... now it's tough but definitely do-able.  I do still feel like I get a great workout in... and it works muscles I don't usually use.  I think overall fitness is a great goal... not just the ability to run miles or fast miles, but also having strength.  It can't hurt right?
