Is there such thing as a nice pain, I could feel the burn in my lungs and to top it off I had a awful stitch pain in my right side for 3 sets of the session and to try and reduce the pain I was taking deep breaths and holding my breath for as long as possible to keep the stretched, I also was try to stretch my side out but the other runners kept on telling me that I looked like a monkey or a tea pot so I only did it when I was out of sight. Todays set was: 5 x 2min, 1min, 1min, 30sec, 30sec, 30sec I completed this session at a high intensity and kept my heart rate high, I've done this session before but we only did 4 reps so we gained a level.
