This weekend, I will be running a Urban Environmental Challenge with my friends in Van Cortlandt Park, Bronx. For my final preparation, I ran for a 3.6 mile route, from my apartment to Roosevelt Island and back. During my run, I did 210 push-ups, 200 crunches in several ways (e.g. bicycles, v-ups, whole body), and 10 sprints on a hill. Although I only exercised for an hour, I made my heart rate going up and down constantly. My workout was efficient and effective. If you’d like to join me for a Guinea Pig Urban Environmental Challenge, feel free to leave me a note and we will run hard until our lungs start burning!
