This advertisement (from Femina’s first issue in 1901) speaks for itself:
“No more anemic young women!”
With daily use of the Sandow home exercise system even “the most feeble” will quickly (immediately) acquire “strength, health, appetite, color, agility, flexibility, gracefulness and nimbleness.” And it fits neatly in your bathroom.
Scholar, Writer, Teacher 
Very practical even for today. Hard to imagine this was 1901.
