A rollable exercise device is formed as a carriage having multiple sides, a main bearing embedded in a concave center, and a removably insertable weight with gripping handle. The main bearing facilitates rolling engagement with the weight and allows for dynamic adjustment of gripping angle relative to the carriage. A bottom surface of the carriage supports a plurality of rollerballs by means of bearings that facilitate omnidirectional rolling engagement of the carriage on a planar surface. Components may be embedded into the sides for attaching external equipment or to attach the device in tandem to a similar device.

A biofeedback belt system which serves as an alert belt with the ability to decrease stomach size as well as decrease the arch of a user-wearers lower back. The invention is designed for patients who have hyper lordosis conditions. The mechanism of the belt is based on biofeedback. When a user-wearer relaxes their abdominal region, the belt produces vibration or sound and the user-wearer must tighten their abdominal region to discontinue the vibration or noise. Biofeedback belt system can also work in a manner such that when the user-wearer tightens their abdominal region, the belt plays music or favorable vibration separately or together as encouragement. Over a period of time of tightening of the abdominal region on a regular basis, the abdominal region size decreases and abdomen strengthens.

An exercise device includes a lower base and an upper platform with a support frame extending angularly therebetween. The angularly extending support frame extends between the lower base and the upper platform at an angle sufficient to allow for a user to position their body in a generally vertical plank position and hold their body in a straight line, angled relative to the floor between approximately 85 degrees to approximately 75 degrees. An exercise system may include a discrete upper platform and a discrete lower plank positioning platform, each of which are removably mountable to a support frame. The support frame, for example, may be a part of another exercise device or may be a discrete stand-alone support frame specifically configured for exercise system

A method and a cushion extension for an exercise device are provided. The cushion extension includes a first portion covering a surface of the exercise device, the covered surface configured to contact the user during an exercise, a second portion extending from the first portion in a direction of the exercise, and a third portion and a fourth portion each joined to opposite ends of the first portion and each forming a method of attachment between each and the first portion.

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 device includes a pivot adjustably positioned at an intermediate point along the length of an elongate support element. One or more lower body supports are mounted on the elongate support element on a first side of the pivot and one or more upper body supports mounted on the elongate support on a second side of the pivot. The device may be used in push up, sit up, inverted pull up or leg raise modes.

An abduction-adduction exercise device is provided. The device may have a handle having a first handle end and a second handle end and an axial handle length. The device also includes at least one hand grip movably attached to the handle and capable of axial translation along the axial handle length of the handle. The hand grip is coupled to at least one resistance means providing elastic resistance to axial translation of the hand grip along the axial handle length of the handle.

An exercise equipment configured to exercise muscles by require the muscles to generate torque intermittently is provided. The exercise equipment includes a sleeve. A pipe is slidably disposed within the sleeve. The sleeve is concentric to the pipe wherein the outer surface of the pipe is spaced apart the inner surface of the sleeve. A counterweight is mounted to at least one end of the pipe wherein the rotation of the pipe along an orbital path causes the pipe to turn within the bore of the sleeve. The turning of the pipe is a result of the counterweights completing a revolution as the counterweights rotate about the longitudinal axis of the pipe. The turning of the pipe generates a pulse so as to actuate muscular structure within the body of the user.

An exercise device that effectively targets and engages the abdominal and core muscles. The device includes a backrest, a first graspable pole, a second graspable pole, a height-adjustable headrest, and a rocking base. The rocking base acts as the supporting structure and includes a first rocker, a second rocker, and a bridge. The first rocker and the second rocker are connected to the bridge on either side. The backrest receives a user's back and is adjacently and pivotably mounted to the bridge, opposite the first rocker and the second rocker. The first graspable pole and the second graspable pole are positioned opposite to each other across the backrest. The first graspable pole and the second graspable pole are each laterally and rotatably mounted to the backrest. The height-adjustable headrest is centrally mounted in between the first graspable pole and the second graspable pole to receive the user's head.
