An adjustable resistance exercise machine for providing variable resistance forces on a pull cable extending from the machine. The adjustable resistance exercise machine generally includes a plurality of power springs that may be selectively engaged using an adjustment mechanism. By engaging springs with different forces, the resistance may be adjusted incrementally as preferred for performing different exercises. The adjustable resistance exercise machine may be connected to various structures, either below or above an exerciser, to allow the exerciser to choose whether to pull the pull cable up or down during exercise.

An exercise machine with electromagnetic resistance selection for changing exercise resistance settings by engaging more or fewer resistance biasing members using a electromagnets. An example implementation includes a movable carriage configured to move substantially along the length of one or more rails. A plurality of resistance biasing members are removably attachable between a stationary biasing member bracket affixed to the machine structure and the movable carriage. A controller changes the resistance settings against the movable carriage by electrically attaching or detaching any preferred number of resistance biasing members between the machine structure and movable carriage.

An exercise apparatus including a stationary exercise apparatus and a lever arm pivotably biased about a pivot axis. A support supports the lever arm above the stationary exercise apparatus, and a biasing device rotatably biases the lever arm with respect to the support about the pivot axis. The pivot axis extends substantially in a vertical direction, and the stationary exercise apparatus is a treadmill.

A sporting device includes a fixing structure, a wheel and an elastic assembly. The wheel is disposed on the fixing structure. The elastic assembly is disposed on the fixing structure and selectively linked with the wheel. When the wheel is unlinked with the elastic assembly, the elastic assembly would not be driven by the wheel, when the wheel is linked with the elastic assembly, the elastic assembly storages a force by driving the wheel.

An exercise and flexibility assessing apparatus includes a handle having a flexible member opening and a latch opening formed therein. A shaft support is mounted in the handle. The shaft support has a first wall and a second wall, distal from the first wall. A spool is rotatably mounted between the first wall and the second wall. A flexible member with indicia for assessment has a first end fixedly connected to the spool and a second end extending outwardly from the handle through the flexible member opening. A latch mechanism has an activating portion that extends outwardly of the spool toward the latch opening and a latching portion pivotally engaging the first wall. The latching portion is movable between a first position wherein the spool is rotatable with respect to the handle and a second position wherein the spool is fixed with respect to the handle.

A device and method for exercising that includes a main axle, a cord spool attached to the main axle, a cord wrapped around the cord spool, resistance modules, and a resistance selector. The drum of each resistance module attaches to the main axle. The drum of each resistance module is attached to a spring configured to resist the cord being pulled from the cord spool. The drums of the resistance modules are configured with engagement patterns that allow for the drums of adjacent resistance modules to couple together. The resistance selector determines how many resistance modules are coupled together. The resistance level of the device can be adjusted to the desired resistance level by coupling together the desired number of resistance modules.

The present invention discloses a multifunctional abdominal exercise wheel, comprising a main body, support members, a central pipe fitting, and a spring barrel. Two ends of the central pipe fitting are each provided with a support rotating member. The support rotating member is pivoted to a support member. The central pipe fitting is inserted into the spring barrel and fixed. The spring barrel is provided with a power spring. The main body is fixedly provided with a single-chip microcomputer, and a display apparatus, a sensor, and a button separately electrically connected to the single-chip microcomputer. Therefore, motion data can be displayed, the stroke and resistance of the abdominal exercise wheel can be adjusted, torsion outputs are stable, and springback noise is small.

An apparatus for exercising having a frame assembly defining a triangular prism shape, which has a frame top bar that has connected a first set of frame lateral bars and a second set of frame lateral bars. The frame assembly further has first and second frame base bars and first and second frame lateral base bars. First and second clamp assemblies are mounted onto the frame top bar. The apparatus for exercising further has first and second band assemblies, a strap assembly, first and second upper handle assemblies, and a board assembly, which are removable from the frame assembly. The frame assembly is used for exercising alone and/or in conjunction with the first and second band assemblies, the strap assembly, the first and second upper handle assemblies, and the board assembly.

A portable exercise device for exercising the muscles of the upper body and thighs. The device comprises a pair of elongate members having a body engaging element for receiving the thighs of the user to hold the device in a stable, fixed position, a spring portion that joins the elongate members in a generally parallel configuration, and optionally a pair of handgrips at the ends of the elongate members. Methods of using the device of the invention are also provided.
