A resistance kickboard attachment is disclosed. When attached to a kickboard, the resistance kickboard attachment adds resistance while swimming with the kickboard. The resistance kickboard attachment includes a resistance pocket, with variable resistance provided by an adjustment of a rear aperture of the resistance pocket. The resistance kickboard attachment attaches to the kickboard with a transverse and a longitudinal strap. The transverse strap includes an adjustment on either side of the longitudinal strap which allows the longitudinal strap to be centered on the kickboard.

A stepper exercise apparatus may include a frame pivotally supporting two pedals connected to the frame. Two cylinders are pivotally connected to the two pedals and to the frame. The pedals may be interconnected to move in coordinated movement in opposite directions. The cylinders provide exercise resistance to the force alternatively applied to the pedals by the user. An exercise resistance adjustment assembly may be actuated to adjust the exercise resistance setting of the stepper exercise apparatus.

Disclosed is a hydraulic damping device with adjustable resistance and a riding platform. The hydraulic damping device with adjustable resistance comprises a support frame, a rotating mechanism movably connected to the support frame, a hydraulic damping mechanism arranged at one end of the rotating mechanism and an inertia wheel detachably connected to an other end of the rotating mechanism, and the hydraulic damping mechanism comprises a shell and a rotating disc connected with the rotating mechanism extending into the shell, at least one blade is arranged on the rotating disc, and the blade is connected with the rotating disc in an adjustable angle to provide resistance at a corresponding angle. The angle of the blade relative to the rotating disc is adjusted so that when the blade rotates with the rotating disc, different from the resistance generated by the damping liquid in the shell, different resistance effects are provided.

A cross country skiing exercise machine is disclosed. The machine has ski members slidingly mounted to a base frame and front and rear arm exercise units mounted towards the front and rear of the base frame, respectively. The front arm exercise unit has a front pair of flexible lines to be gripped by a user's hands to permit the user to reciprocally pull back on said front pair of flexible lines. The rear arm exercise unit has a rear pair of flexible lines having straps configured to be attached to the user's arms to permit the user to reciprocally pull forward on the rear pair of flexible lines. The front and rear arm exercise units are configured to apply a drag force to the front and rear pair of flexible lines, respectively. A rear leg exercise unit having flexible lines for mounting to the user's legs is also provided.
