A limbs cooperation exerciser and a control method for the same are provided. The limbs cooperation exerciser includes a frame, an upper limb exercise mechanism, a first driving module, a lower limb exercise mechanism, a second driving module, a first rotating speed sensor, a second rotating speed sensor, and a control module. The control module controls at least one of the first driving module and the second driving module according to the first rotating speed and the second rotating speed, making a differential value between the detected first rotating speed and the second rotating speed be smaller than or equal to a predetermined differential value. That is, the limbs cooperation exerciser controls the rotation of the first operating member or the second operating member to lower the difference between the rotating speeds of the first operating member and the second operating member.

An exercising equipment having base formed of a U-shape pipe; first and second arms, each rotatably connected to the base and having a securing knob engageable to affix the arm at an acute angle to the base; first paddle rotatably connected at a first connecting point to the first arm; second paddle rotatably connected at a second connecting point to the second arm; foldable connecting bar assembly connected at one end to the first paddle and at the second end to the second paddle, to thereby form an S-shape together with the first and second paddles when assuming an extended position and form a W-shape together with the first and second paddles when assuming a folded position; and, at least one variable friction pivot assembly attached at the first or second connecting points thereby applying variable friction to rotation of at least one of the first or second paddles.

A treadmill includes a frame, an exercise deck attached to the frame, and a first handle movably attached to the frame. The first handle has a first orientation where the first handle is positioned within a region above the exercise deck and stabilized to support a user's weight during a body weight exercise, and a second orientation where the first handle is positioned away from the region above the exercise deck.

An exercise machine resistance adjustment system for providing an exerciser the ability to immediately adjust the resistance force by changing their body position on the movable carriage or end platforms. The exercise machine resistance adjustment system generally includes a frame, a carriage movably positioned on the frame, a spring connected to the carriage to apply a biasing force to the carriage, one or more left projections within the carriage adapted for a left hand of an exerciser to grasp, and one or more right projections within the carriage adapted for a right hand of an exerciser to grasp. The exerciser is able to efficiently adjust the amount of resistance force applied to the carriage by repositioning their hands (or feet) from a first set of projections at a first distance to a second set of projections at a second distance from the first end of the exercise machine.

An aqua resistance dumbbell comprises a tubular wall that provides a bore for receiving a user's hand from each end of the bell. A rod is located within the bore and extending laterally across the bore to be gripped by a user with one or both hands from one or both ends of the bore. The dumbbell has a plurality of longitudinal fins extend along the tubular wall on an outer side of the tubular wall, and at least one lateral fin that extends laterally at least part way around the tubular wall. An aqua resistance fin assembly comprises two fin components and at least one fastening member for fitting the fin components to a user's limb in a side-by-side configuration around the limb. Each fin component comprises a base adapted to fit against a user's limb and adapted to be secured to the user's limb by the fastening member, and at least two longitudinal fins and at least one lateral fin on an outer side of the base.

A reversible resistance exercise machine for reversing the direction of applied resistance against a movable platform of an exercising machine. The exercise machine has a frame, a carriage movably positioned upon the frame, and a plurality of biasing members. A plurality of first tension connectors are accessible near the first end of the carriage and are adapted for removably attaching selected biasing members near the first end of the carriage to resist motion of the carriage in the first direction. A plurality of second tension connectors are accessible near the second end of the carriage and are adapted for removably attaching selected biasing members near the second end of the carriage to resist motion of the carriage in the second direction. A user selectable amount of force may be applied to the carriage to resist movement in either of the first direction and the second direction.

An exercise machine rail indicia system for providing indicia to improve exercise instruction. The exercise machine rail indicia system generally includes a frame a rail, a carriage movably positioned upon the rail, a bias member connected between the carriage and the frame that applies a bias force upon the carriage, a first position indicator positioned upon the upper surface of the rail, and a second position indicator positioned upon the upper surface of the rail. The first position indicator and the second position indicator are distally spaced apart a first distance. The first position indicator and the second position indicator visually indicate to the exerciser where to position the carriage along the first rail during the performance of an exercise.

An exercise machine carriage handle system for providing handles for an exerciser to grasp with their hands thereby expanding the type of exercises that may be performed. The exercise machine carriage handle system generally includes a frame having a track, a carriage movably connected to the track, a bias member connected between the frame and the carriage, a first handle connected to the carriage near the first side, and a second handle connected to the carriage near the second side. The first handle and second handle are adapted for grasping with a first hand and a second hand respectively of a user during the performance of an exercise on the exercise machine.

The present invention relates to the field of fitness training devices and exercise machines. More specifically, a substantially horizontal exercise machine comprising an exercise platform slidable along one or more rails aligned with the longitudinal axis of the machine structure, the slidable platform spring-biased towards one end of the machine, is tiltable to allow for one end of the machine to be raised or lowered relative to the opposed end of the machine.

An exercise machine resistance adjustment system for providing an exerciser the ability to immediately adjust the resistance force by changing their body position on the movable carriage or end platforms. The exercise machine resistance adjustment system generally includes a frame, a carriage movably positioned on the frame, a spring connected to the carriage to apply a biasing force to the carriage, one or more left projections within the carriage adapted for a left hand of an exerciser to grasp, and one or more right projections within the carriage adapted for a right hand of an exerciser to grasp. The exerciser is able to efficiently adjust the amount of resistance force applied to the carriage by repositioning their hands (or feet) from a first set of projections at a first distance to a second set of projections at a second distance from the first end of the exercise machine.
