Hi, this is Kiya Knight, exercise scientist and creator of "WEightless Worldwide: The Evolution of Mind-Body Fitness." And today, I want to teach you a couple tricks for increasing fatigue in daily life. If you have a job where you sit at a desk for most of the day, or if you spend long hours in your car, you know that's important to find little ways during the day to increase the amount of calories you're burning so that you don't put on excess weight over time. Now, the Mayo Clinic actually did a big study on non-exercise thermogenesis, and what they found is that individuals who stood at their desks instead of sitting actually burned in excess of 60 calories more per day than individuals who were sitting. So, just by raising your desk to a standing position you're already going to increase your output of calories during the day. Another thing that you can do in order to increase your fatigue is toe tapping. Another really powerful way to increase the amount of calories that you burn during the day is by adding a little bit of active internal resistance, or what I like to call, "air." So, I use three points in my body in order to draw a lot of energy into my core center -- those are my lats, my transverse abdominals, and then also my glutes. So, by just doing a little bit of isometric holding with these three major muscle groups, you're going to be increasing the amount of calories it takes just to be you, and you're also going to be increasing your level of strength and stability. Make sure that if you're doing a little bit of isometric holding you're also waving through your body and moving around. Take a minute to relax your neck during the day and bring your chin to your chest, roll your head from side to side, so that you keep all of your joints really lubricated and fluid. So, in order to increase your energy output during the day, you can use active internal resistance, or you can raise your desk to a standing position -- instead of sitting all day, you can stand up and burn in excess of 60 calories more per day than if you were sitting.
