On the 4th Run Of Christmas...

4 Lunge Miles

How it's done:

1. You are going to do 20 lunges(10/leg) before every mile.
2. Ideally you are doing step back lunges as they are easier to keep good form.
3. The second your last lunge is complete you start running the next mile.
4. 4 total miles and 80 total lunges

This is a great set to learn how to run on fatigued legs.  Think mountain efforts. We use sets like these for people training for mountain runs when they don't have access to mountains.

See you tomorrow for day 5!
