M: We all know that exercise is good for us, but sometimes it seems too hard to leave the sofa. W: I can see that. You seldom do exercise. M: Plus, having the doctor tell us to get two and a half hours’ exercise a week doesn’t really help our motivation much. W: Don’t be discouraged. Now a new study suggests getting benefits from exercise doesn’t have to be that demanding. Jacob Sattelmair from Harvard University has done a study into how much exercise is needed to lower the risk of heart attacks. M: Mmm…, interesting! W: The study showed that people who put in 300 minutes a week of exercise had a 20% lower risk of death due to heart disease. Still, the people who exercise 115 minutes a week did pretty well, too, lowering their death risk by 14%. M: And what about the people who exercise half as much as that, like what I probably do? Does that help? W: Of course, even 15 minutes would help.
