What I learned last night

So last night I did a new workout from the Jillian person who trains people on the biggest loser. we have comcast on demand and her videos on included so it was fun. Anyway her work-outs are SO SO SO hard. my whole body was shaking like half way through and its painful today which is good. BUT, the most important thing I learned was how important warm-ups are before your work-out. I never fully understood why and then I did some research on it. With my pilates I jump right into the video thinking they have got it all worked out for me ya know? wrong. they have the workout but they dont have the warm up. now here is why it is important. compare your body to a rubber band, when a rubber band is cold and you try to stretch it,snaps it in half. well your body is much the same way, if you dont warm up your body first and you try to stretch it and work out, your muscle will in a sense snap and they anything you do after that is pointless. I learned this because the other day, I didnt warm up and I did an exercise where you sit on the floor with your legs straight in front of you and reach for your toes, It hurt and I thought that was normal but for days after that, my muscles felt strained and like I pulled something. SO, before every work out you should do a 5 min warm up, not only to not injure yourself but it makes your entire strength training work-out twice as efficient. YAY!
But for reals, her workouts are rough and good. she combines cardio and strength training and puts in into an interval training program. its about 30 mins and SO SO SO Good. almost better then pilates. lol they are even.
