I had a customer today who is a personal trainer. I did not know this. He asked what I was doing. I explained to him about my new food regime. He asked me about exercise. I told him that I just started and was mainly walking. He gave me some walking tips. I told him that I have weight balls. He gave me some tips for using them. Here is one of them: when you are walking, have a weight ball in each hand. Bring your hands together near your middle and then bring them up till each elbow is parallel to your shoulders. This will help a lot with the underarm wave.
