Rudi is 53 years old. One and a half years ago he decided to put his body to the test to find out whether he could get it into competition-ready shape without the help of testosterone, growth hormone or anabolic steroids. He entered an over 50s natural bodybuilding competition. Added to the challenge – no artificial sweeteners, colors or additives were allowed in his diet and there would be no beef, chicken or turkey products (staples in most bodybuilding diets).

The last time Rudi trained and dieted as a bodybuilder was in his thirties. So, with a 20-year break, he began his adventure.

Here is a pictorial summary of his journey so far.

1993, Rudi was 34 years old and ready for the NSW Natural Bodybuilding competition.

June 2011 and with nearly 20 years off from any serious training, the experiment begins. Will Rudi be able to whip himself back into the kind of shape needed to compete as a natural bodybuilder?

Rudi in Aruba, October 2011

By October, 1 month away from his first over 50s natural bodybuilding competition, Rudi is looking leaner and stronger. Hardest fat to move? Abdominal fat – decidedly stubborn, especially in the 50’s. Hardest area to build? Legs.

Move forward to 2012, nearly a year later. Daily training, strict dieting and supplementation. The abdominal fat is gone. Rudi is looking pretty good. Keep in mind, he’s 100% natural and has been all his life.
