Abstract: A lower body reciprocating exerciser includes a frame having two posts on two sides thereof. Two swing units are respectively connected to the two posts and an arm of each swing unit is connected with a cam of a transmission unit corresponding thereto. The cam is connected with a piston rod of a resistance unit corresponding thereto and the piston rod is connected with a piston located in a cylinder. An enclosed loop pipe is connected to outside of each of the cylinders and includes two sets of a check valve and an adjustable control valve. The loop pipe communicates with the space in the cylinder. The check valves and the adjustable control valves control the fluid in the cylinders to adjust the resistance force when the user swings the pedals and the arms, so that the user's bones and muscles of the lower body are exercised properly.

Abstract: A board apparatus for balance exercises and balance games having a platform that tiltable on a base part, freely rotatable around a vertical axis, and mounted movably along the vertical axis. A restoring part generates restoring forces that counteract motions of the platform and can be modified by the user. The restoring part includes four elastomer springs that are arranged at a distance from the center of the base part. The elastomer springs can be offset inward or outward with respect to the center of the base part, enabling accurate adaptation of the restoring forces. When twisting the platform around the vertical axis, the restoring part always returns the support part into one of two initial positions that are located 180 degree opposite to one another.

Pivoting of the handle with respect to the suspension member couples the arm to the mount to thereby fix the position of the handle along the suspension member.

Abstract: The present invention relates to a standup exercise apparatus that simulates walking and jogging with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet where the pedal stride length is determined by the movements of an operator. Crank arms are positioned on the framework forward the operator at a height comparable to the pedals. Compound guides are used to achieve elliptical curve pedal paths.

Abstract: The means for securing weight plates (16) on weight rods (10?, 12) or holder bars provides at least one groove (14) formed in an end region (10?) of a weight rod (10?, 12) or in the holder bar. The weight plates (16) are formed with a radial protrusion (17) in their central bore, preferably extending over only a portion of the circumference. The diameter of the bore at the protrusion (17) is greater than the diameter of the end region (10?) of the weight rod (10?, 12) or holder bar axially next to the groove (14). The protrusion (17) falls into the groove (14) and prevents the weight plate (16) from slipping off the weight rod (10?, 12) or holder bar.
