Age 63.
I went on a weight training program lifting weights started light worked my way up three times a week walking every day. I worked with a trainer one day a week to make sure that I was in form. I also worked with the Naturalpath and got on a good supplement program based on my blood test to determine what I needed to add. This included such supplements as vitamin D with K2 magnesium Osteo supplements and creatine, etc. I also added in prunes daily upped my calcium through food choices and my protein. And I was on a vibrational training machine four times to five times a week. I also used a weighted vest and did simple exercises in my program such as the farmers carry continuing to increase my weights.
It wasn’t one thing that I did. I think it was a combination of everything just an awareness of what I was putting in my body and consistent weight training program. Yes you can grow muscles at 63 and I am very strong now I love it.
