1. Exercising apparatus, which comprises:

  • (a) track means,(b) first and second oscillating support elements mounted for movement on said track means and respectively adapted to support two limbs of the exerciser using the exercising apparatus,said track means and said support elements being so related that said first and second support elements can oscillate along substantially parallel paths relative to each other,said paths being spaced apart a distance generally corresponding to the distance between the supported limbs of the exerciser,(c) means to oscillate one of said support elements with harmonic motion, with no abrupt changes in speed,(d) means to connect said one support element to the other of said support elements to cause said other support element to oscillate with said one support element in master-slave relationship and 180 degrees out of phase relative to said one support element, and(e) means to change the amplitude of oscillation of said one support element to thereby simultaneously change the amplitude of oscillation of said other support element by the same amount.
