This is the first part of a complete training session that Vilma Siebers, 81, had with Jim Baker at CrossFit Santa Cruz Central, where he is a trainer and co-owner.
Vilma is originally from Berlin. She was a teenager during World War II, and came to California in 1952. She maintains a very active life, training with Jimmy one day a week, going on long hikes with the Sierra Club, line dancing, photographing.
In this video, there is an introductory interview before Vlima and Jimmy go on a remarkably fast-paced 1K walk (taxing the cameramen in the process). At the far point of the walk, they use the sidewalk curb as a beam for various balance drills.
