July 2023 research by Edith Cowan University said
Our previous work has shown regular, shorter exercise is more beneficial than a one or two big training sessions in a week.
Now, we have a clearer idea of where the tipping point is where you start to see meaningful benefits from such a minimal exercise.
These new results suggest at least three days a week are required.
However, it may be that exercising once a week for 2 hours is less effective than exercising every day for 20 minutes.
If it is not possible to have 20 minutes a day for exercise, even five minutes a day makes a difference for fitness and health.
It is important to note that even a very small amount of exercise can make a difference to our body, if it is performed regularly.
