The 25-Minute Sprint Fartlek Workout: “Fartlek” means “speed play” in Swedish. This type of HIIT program combines continuous training with speed intervals. You control the intensity and speed of each interval, so the training can feel spontaneous and engaging. This program focuses on cardio training, where you walk, jog, or sprint for set amounts of time.
Or skip your favorite early-morning show—whatever it takes to grab a few more minutes of sleep each day. When researchers at the University of Chicago studied men who were sleep-deprived, they found that after just a few days, their bodies had a much harder time processing glucose in the blood—a problem common in overweight diabetics. When the individuals returned to a more normal seven to eight hours of sleep a night, however, their metabolisms returned to normal.
When you exercise on the rowing machine, try this interval workout: Row for 60 seconds, note the distance on the machine, then rest 60 seconds. Repeat, only this time, row for 55 seconds and try to match or better your distance from the first time. Rest 55 seconds, then repeat, reducing the time to 50 seconds. Continue until you can’t beat your original distance.
In fact, researchers at Wake Forest Baptist Medical Center found that every 10-gram daily increase in soluble fiber was associated with a 3.7 percent decrease in dangerous visceral fat over five years. Those who were active got even leaner, shaving off twice that much fat in the same amount of time. To start ditching that extra belly fat today, add the best high-fiber foods to your menu!
We just don't feel full by liquid calories in quite the same way as we do real food. Drinking a juice or caramel coffee drink just isn't as satisfying as eating a bowl of veggie- and protein-packed stir-fry. So monitor your intake of juice, soda, sweetened coffee and tea, and alcoholic beverages. If you consume each of those beverages during the day, you'll have taken in at least 800 extra calories by nighttime — and you'll still be hungry. (Incidentally, alcohol may suppress the metabolism of fat, making it tougher for you to burn those calories.)
And maybe a new mattress, because it’s not just the amount of time you spend sleeping that keeps you lean, it’s also the quality of your sleep. Fat cells in your body produce a hormone called leptin that helps the body keep track of how much potential energy (i.e. fat) it has stored. But leptin is only produced during certain stages of sleep. Miss out on those stages because you’re not resting soundly enough, and you’ll disturb levels of the hormone, leaving your body with no real idea of its energy reserves. Consequently, you’ll end up storing calories rather than burning them.
