This exercise is perfect for those who aren't able to run very far without stopping! This workout can be done on the treadmill or outside! Interval training is super helpful to build up speed and endurance!
If you are using a treadmill, put the incline at a 2-4 to avoid knee injury.
1/2 mile warm up (walk)
1/2 mile run (should be a medium comfortable pace that you are able to keep for half a mile)
1/2 mile walk
Repeat for 3-5 miles! This workout is so great because even if you can't run long distances, you'll be suprised at how many miles you can actually go when you implement these intervals!
