Running Right (01 of09)
Open Image ModalYou Crane Your Neck To Watch TV (Or Your Feet)(02 of09)
Open Image ModalAnything that throws off your posture, whether it be hunching over to watch your feet or leaning to the left for a better view of the TV, is generally a bad idea. "Your neck is pulled to the right or dropped forward and one part of the musculature is getting stretched while another is getting tightened," says Basso. The longer you're in that position, the higher your risk of injury becomes, he says.You're also likely to offset your balance, warns Karp. "You're looking to the left or to the right and your body's going to follow a little bit," he says.Slumping over can also limit your oxygen intake, says Cardiello. To guarantee you're standing your tallest, imagine someone is pouring ice water down your spine, he says.For those runners who rely on a little screen time at the gym, try to find a treadmill with a screen attached, says Cardiello, so you can face forward with your chin parallel to the ground. If your gym isn't equipped with those machines, head to the back of the room. That will keep your neck as straight as possible while still allowing you to watch overhead TVs, he says. "Keep your head, heart and hips inline when you run," he says. "You're running over the ground, never into the ground." Or the belt, as the case may be. (credit:GETTY)
You're Too Zoned Out(03 of09)
Open Image ModalClearing your mind with your favorite TV show during your run is one thing. Jumping on the treadmill with concrete fitness goals is another. "I think a lot of people who choose to use cardio equipment, yeah, they sweat, but your mind starts to wander," says Basso. "Instead of really being present and focusing on the exercise, your gait, your posture, people lose it there." A too-engrossing book or magazine, or a movie might be too distracting, says Cardiello. "Save the reading for your cooldown." (credit:GETTY)
You Do The Same Thing Over And Over(04 of09)
Open Image ModalYou Skip The Warmup(05 of09)
Open Image ModalYes, you're busy. Some days you just want to hop on the treadmill, get it over with and get out. But skipping a warmup can lead to pain and injuries, says Basso. You don't need a lot of time, and you don't need to passively stretch, he says. Instead, take five to seven minutes for an active warmup with a "joint-by-joint approach," he says, that includes hip circles, toe touches and more. "It's more of a priority to keep your mobility and keep yourself out of pain than to start a workout," he says. (credit:Getty Images)
You Hold The Bars(06 of09)
Open Image ModalHolding onto the handrails on the treadmill might seem like a safety measure, but your workout will suffer, says Karp. Some of your bodyweight will be supported, meaning you won't have to work as hard and you won't burn as many calories, he explains. If you feel like you need to hold on, it's probably because you're going at a slightly faster speed than you're ready for, he says. "Get comfortable without holding on in increments to gain confidence at each speed," he suggests. (credit:Getty Images)
You Set The Incline Too Steep(07 of09)
Open Image ModalHow often do you encounter a steep hill in the outside world that takes you an hour to climb? Exactly. Exercise should be functional, says Basso, and strengthen your muscles for real-world use. Plus, the steeper that incline, the more likely you'll be holding onto the bar to keep yourself on the belt. "If you have to hold on, it's either too fast or too steep," says Karp. (credit:Getty Images)
You Trust The Settings(08 of09)
Open Image ModalBetween the heart-rate monitor grips on the handrail and the button for the "fat-burning" zone, there's not much worth trusting on that digital dashboard. "You can't really rely on those," says Karp. "The mathematical formulas are rough estimates based on a lot of variables," he says. And every runner is different. Since they're probably not accurate to begin with, says Cardiello, don't obsess over the numbers on your machine. "Throw a towel over the display," he says, and you might just find you work a little harder. (credit:Getty Images)
You Jump Off With The Belt Moving At Full Speed(09 of09)
Open Image ModalIt might seem like taking a water break without slowing down the belt saves you time in the longrun, but not if it makes you trip and fall first. "Most people don't have the coordination to do that without risking injury," says Karp. "I see people all the time who come close to falling."Fess up, are you guilty of any of these?
