Exercise for Beginners!

Hey girls, I would like to commit to your forum for beginners!! Ive always been good about exercising when I have someone to check in with, but when its just me I might say that I slack a little...well...a lot! Today was the first day that I did any exercise and I must say my shoulders and arms are pretty sore. Working to get the baby weight off of my twin pregnancy. So today I did a Ballywood dance video (which was way fun), 30 crunches, 10 pushups, and 10 bycycles. Not a lot but my tummy muscles are still really tender and not wanting to push it too much until they get a little more strength back.
