No wonder I never “saw” any changes when I was training for whatever race…
I felt better, but didn’t “see” a change in my body:
“The secret is intervals. Study subjects who spent just 20 minutes mixing sprints with jogging lost three times the fat off their legs and butt in 15 weeks, compared to those who jogged steadily for 40 minutes, research from the University of New South Wales in Sydney finds. Intervals may spark fat-mobilizing hormones, and they amp your cardio capacity so your future runs will actually feel easier.I like relaxing runs, but if you do the same slog every day, you can suffer from what’s sometimes called “postman’s syndrome”—named for those who do the same walk every day and yet their bodies never change. Your muscles become so efficient at a movement over time that if you do it day after day and eat the same way, you never overtax your system and burn more calories to lose weight.
The answer is to mix up your cardio either by changing your workout around or adding speedy bursts—meaning intervals. Intervals can be fun if you approach them right. Each one represents a mini goal—finish the 1-minute sprint, complete the 2-minute cooldown, and so on.”
