What Is Interval Training?

Why Some People Prefer Intervals Outside
Some runners like doing intervals outside because:
- They enjoy fresh air and nature.
- They can run different surfaces like grass or trails.
- It feels less boring than running on a treadmill.
- They can change routes and scenery.
But the treadmill is a good choice when weather is bad or time is short.
How Often Should You Do Intervals?
For most people, 2 to 3 interval workouts a week is good. Do not do intervals every day. Your body needs time to rest and recover.
On other days, do easy walking or jogging. Or try other exercises like cycling or swimming.
