I can’t believe this, so I just had to share! About a month ago, I moved some heavy furniture and since then had experienced serious knee pain from a previous injury. It was difficult going up and down stairs, so at work, I would take the elevator, even to go up or down one floor. Well, yesterday was my first day using the NutriBullet. I had a Nutribullet breakfast and dinner. This morning, when I got out of bed, I noticed I didn’t have my usual back pain and I didn’t have to take one step at a time in my condo. It took me a minute to realize I wasn’t feeling any pain. So, when I went to work I decided to try the 24 stairs in the office and I made it up, without any pain! About 5 minutes later, I went back down; still no pain! I hadn’t done that in over a month! I’m just amazed!!!!
