Eugen Sandow was a German strongman, circus performer and strength athlete considered by historians to be the “father of modern bodybuilding.”
Sandow’s physique was known around the world as he pioneered the concept of training the body to achieve a specific look. More importantly, Sandow made popular the notion of exercising for good health.
Lie flat on the back on the floor, couch or bench, covered by a rug, at full length, the arms close by the sides, the feet pushed under the bureau, weighted or strapped to the floor, to give purchase to the body; then alternately raise the body on the hip joints, from the supine to the sitting position, and slowly lower it again to the horizontal position, repeating the movements until the abdominal muscles feel the tiring effect of the exercise.
