Well, I started my cutting cycle and I've been doing great with my diet so far. I did some light running on a treadmill to get me back into some kind of cardiovascular shape before I start HIIT cardio in January. However, I have noticed that my back gets sore during running and also remains sore... I did cardio today and its still sore at midnight tonight. Am I running funning? It seems as though I'm jarring my back or something? Maybe I run too flat-footed? I could really use some input on this.

I'd really like to keep using the treadmill as I have one available at my apartment so its handy for now.

Thanks,
