How to Effectively Combine HIIT Sessions with Endurance Cardio
Ladies and gentlemen, may I have your attention please: walking or jogging for hours on the treadmill, peddling for hours on the stationary bike, climbing a mountain on the StairMaster, and plodding away on the elliptical trainer is NOT the best way to burn calories!
We’ve seen a hundred studies telling us that high intensity interval training (HIIT) burns more calories and fat, speeds up your metabolism, and is less catabolic than hours of endurance cardio. HIIT can also be far less boring, will actually help you build more muscle tissue, and increases your resting metabolic rate.
HIIT: Twenty minutes of HIIT cardio improves your VO2 max, burns a ton of calories, increases your metabolism, and maintains or builds muscle tissue all at once.
Endurance Cardio: Sixty minutes of endurance cardio is not only boring as hell, it also increases cortisol, burns muscle tissue (protein) for energy, and halts protein synthesis.
