My change up the workout was simple but I'm enjoying it. I've simply added running to my work out. I have bad knees so it makes it hard to run too much. Since I've lost some weight and gained some muscle and endurance, I can run. Now I use the term run very loosely, but it's a work out for me. I do my regular work out variations and then add a run walk alternating at the end. This challenge was just perfect for me since I was feeling discouraged to not have lost more weight. Just the change up I needed to start seeing results again.
