The present invention relates to a comprehensive fitness equipment leg press allows a user to do a weight training leg press exercise for training a lower body from 10 kg to 200 kg by sitting on a bench pushing the footrest included in the footrest frame, which moves back and forth smoothly along a central frame for adjusting weight of the footrest frame. The comprehensive fitness equipment leg press comprises a hydraulic cylinder formed on a lower end of the bench without using 15 10 kg weights and a hydraulic cylinder rod connection installed on a body of a weight adjusting bar using the principle of the lever for adjusting weight of the footrest of the footrest frame.

An exercise treadmill is disclosed. The treadmill can be constructed with no obstructing front rails, with one or more side rails, and/or with a structural flat or ramped surface at the front allowing the user to exercise with unconstrained motion. The treadmill can further include one or more accommodations to help the user stay safe, remain longitudinally centered, and/or adjust speed with controls built into the treadmill, or automatically based on body position relative to sensors built into the side rails. The treadmill belt may be motor driven, or be user driven and dynamically moderated by resistance. The treadmill configuration can be utilized to provide a virtualized exercise experience for the user.

An exercise apparatus and a method of using the exercise apparatus are presented herein. The exercise apparatus includes a handle portion and at least two angularly spaced resistance elements which, in use, are attached to the handle portion for providing resistance to movement through a liquid. The method of using the exercise apparatus includes immersing the exercise apparatus in a liquid, holding a handle portion of the exercise apparatus and exercising by moving the exercise apparatus against resistance provided by the liquid.

Described herein are various embodiments of differential air pressure systems and methods of using such systems. The differential air pressure system may comprise a chamber configured to receive a portion of a user's lower body and to create an air pressure differential upon the user's body. The differential air pressure system may further comprise a user seal that seal the pressure chamber to the user's body. The height of the user seal may be adjusted to accommodate users with various body heights.

A crank-driven exercise device (100). The crank-driven exercise device (100) includes a frame (102), a spindle (202) rotatably connected to the frame (102), a crank arm (104) connected to the spindle (202), and a user input (208) connected to the crank arm (104) configured to receive a force from a user. In some embodiments, the crank arm (104) includes a proximal section (204) and a distal section (206). The proximal section (204) may be connected to the spindle (202) at a spindle interface (302), the distal section (206) may be rotatably connected to the user input (208) at a user input interface (306), and the distal section (206) may be selectively fastenable and selectively rotatable relative to the proximal section (204) at a crank interface (304).

An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine adjustable resistance system and method generally includes a control unit in communication with a resistance adjustment system of an exercise machine and a biometric monitoring device used by an exerciser on the exercise machine. The control unit receives biometric data from the biometric monitoring device and sends a control signal to the resistance adjustment system to adjust the resistance of the exercise machine based on the biometric data received.

A modular exercise system is described wherein the system utilizes a universal hydraulic actuator attached to a mount. A connector is attached to the universal hydraulic actuator opposite the mount. The universal hydraulic actuator preferably comprises two hydraulic rotary actuators with non-parallel axis of rotation.
