How to run faster ?

If you want to get some speed in your running and build up your VO2 max you can mix this workout 2-3 times per week with your regular workouts on the other days.

First jog for about a mile to warm up and stretch you muscles

then do this for 5-10 times

Run half a mile at 10-20 seconds under your current mile pace
rest for two minutes (walk or jog if you can)

Explanation: lets say you run a mile in about 8 minutes that is 480 seconds, your half a mile pace would be 240 seconds, you should try to run it in about 220-230.

What is VO2 max?

It is your maximal oxygen uptake, it is your body's maximum capacity to transport and use oxygen during your exercises.
