A new study suggests that doing all your exercise on the weekend can be just as good for you as spreading it out throughout the week.
Researchers found that people who squeezed all their exercise into one or two days had a lower risk of getting sick, compared to people who didn't exercise at all.
This means that if you're busy during the week, you can still stay healthy by doing all your exercise on the weekend, as long as you get enough.
It's all about the total amount of exercise you do, not how often you do it.
