It's time to shed some fat and reveal the strength you are building. Not to mention stay healthy and vibrant. The benefits of this workout go far beyond appearance. See how I keep my cardio workouts enjoyable by going outdoors and keeping it quick and intense and racing against the clock!

Here's how the workout goes:
Run to the park: 5 mins
find a stairs or a hill, run up and down 3 times, 10 pushups at the top and repeat. 
Try to complete the repeats as many times as possible within 10 minutes time period
Run back 5 mins.
There you have it, a fast, effective, 20 minute workout that anyone can fit into their busy schedule. 
Hope you enjoy!
