I did two workouts today. I did the usual 60 mins on the elliptical, and then later in the afternoon, I took the dogs on a walk and ended up getting hot and sweaty since it is so hilly around here, so I thought, hey why not do another workout on the elliptical. I would have just watched TV or gone on the computer, so better to get on the elliptical and do that while watching TV.
Since I don't have a job right now, I figure I should do something good with this time and be productive.
My friend Erin (at Erin's 6 Month Transformation) was talking about doing double workouts too and said that maybe working out twice a day would keep metabolism up even more since after you exercise it takes a while for it to go back down. And if that happens, all the better!
So I looked it up and that is exactly true. Working out twice a day will obviously allow you to burn twice the calories, but give you that increased metabolism rate for the few hours right after the workout - twice!
Basically doing anything to get your heart rate up more times during the day is a good thing. Kind of obvious, but it's good to know and a good motivator to keep up with the double workouts.
