In the latest issue of Men's Health magazine, there's an article hypothesizing that workouts that mix up cardio/strength and toning burn more cals (or drops away more fat) than simply running for that same amount of time. So though your heart rate isn't pumped the whole time lifting/toning/combining like it is with running, you still burn the same amount and lose even more fat.
I dared myself to try it for a bit, starting today: instead of 30 mins of running w/ 60 sec sprints followed by jumping rope/dancing/light weights for 20 mins, I swapped. I did 20 mins running/sprints and 30 mins jumping rope, lifting and dancing. My muscles were screaming from being challenged in new ways. I feel it in my body tonight, too. Now, wonder if it'll help me maintain or lose more with this strategy? Any one else have experience or input regarding this? Thanks!
