The York Adjustable Crusher

Posted on Monday, April 27th, 2015 by John Wood
“The York Adjustable Crusher Body Developer is a new York feature and one that will provide novelty and diversion in your training. Being adjustable, its resistance can be increased or decreased to match the strength of any enthusiast. Muscles respond readily to this form of training because it is concentrated action. Employ as many springs as your strength will permit to complete the specified number of repetitions. In movements where one arm is exercised, be sure to repeat an equal number of repetitions with the opposite arm.”
