You get more benefits from your mileage if you move a little all day.
Sitting kills. We’ve heard the message loud and clear – but recent studies suggest it’s not the whole truth. “Stagnicity, or remaining in a fixed position for a long period of time, is the health hazard,” says chiropractor and physiotherapist A.J. Gregg. The seated-in-a-chair position is simply where most of us clock all that motionless time. And while runners may not think they are all that sedentary, research shows exercisers are parked almost as much as their inactive pals –about nine hours a day.
“The body is meant to move,” says Gregg. When you’re motionless, the hamstrings, lower-back muscles and hip flexors can become tight – conditions that can hinder running performance and leave you hurt. Sitting allows your glutes to sleep all day, too. When that major muscle group is weak or underutilised, you bring less power and stability into your workouts, and you overwork smaller nearby muscles in ways that could lead to injury. Meanwhile, sitting slows your circulation and turns off fat burners, upping your odds for heart disease, cancer and diabetes. Ready for some good news? There’s a relatively simple fix: “By bringing more movement into your non-exercise time, you can engage forgotten muscles and offset some of those sitting effects,” says biomechanist Katy Bowman, author of Move Your DNA. “It doesn’t have to be intense, it just has to change your geometry.”
