Interval Training Beats Belly Fat
As we age, muscle tends to be replaced by fat that gathers in our bellies and raises our risk for heart disease. But at least some of that belly fat can be reversed with interval training, which alternates short bursts of intense activity with longer intervals of less-intense activity. In a study, 36 older adults with belly fat performed interval training, starting slow and working their way up to 36-minute sessions three times weekly. Exercises included jumping jacks, push-ups, squats, and sprints, with short rests in between. After 10 weeks, they’d dropped nearly 2 pounds of fat and gained about a pound of muscle compared with 36 similar adults who didn’t do interval training. The effect was greater for men than women. Of course, always check with your doctor before starting any exercise regimen. And, like the 70-year-old participants in this study, start small and build up to longer sweat sessions.
