A dumbbell with a selectable number of weight disks includes a handle with pins projectable in opposing directions, a base assembly for accommodating two sets of weight disks standing upright, and having through-going openings. Neighbouring weight disks have mutually cooperating connecting arrangements which axially interconnect the weight disks but which permit radial separation. The projection lengths of the pins are stepwise selectable in order thereby to permit selection of the number of weight disks carried on the handle. The handle has, in opposing ends, connecting arrangements for interconnecting with the connecting arrangements of the innermost weight disks in the base assembly. Further, the space between the connecting arrangements of the handle is free through 360 about the handle throughout its entire length, the openings of the weight disks being centrally located.

The present invention is a device configured to permit combining the weight of a first and second free weight such that a user could grasp one of the weights in order to lift the combined weights. Embodiments of the invention comprise a back panel connected to two side panels, the side panels each comprising a slot with an opening divided into two portions oriented such that a first free weight may be inserted into the slot of each panel and positioned into a first slot portion, followed by a second free weight positioned in the second slot portion of each panel to permit a user to increase the resistance available for an exercise regimen.

An apparatus for receiving one or more activity attachments including a deck having one or more openings along a long axis of the deck and between the top surface and the bottom surface of the deck. Each of the one or more openings having a circular aperture for receiving an accessory of a set of accessories. Each accessory of the set of accessories providing an activity for a user of the activity. Each accessory having an attachment platform configured to attach the accessory to the board. The attachment platform having a locking mechanism to engaging with a complementary locking mechanism of the board.

An exercise apparatus comprising: a foot support, a user interface that includes a visual display, the foot support being movable by the user on the frame back and forth through any one of a plurality of complete, reproducible and different arc segments of a master arcuate path, the foot support being interconnected to a selection device that enables the user to select any one of the plurality of arc segments, one or more detectors adapted to detect one or more of force, energy or power exerted by the user over time on the foot support or distance or velocity of travel of the foot support or resistance assembly during the course of the user's performance of all or a portion of an exercise cycle, the visual display displaying a visually recognizable format of one or more of the force, energy, power, distance, time or velocity.

Systems and methods for fitness tracking are provided. An exercise apparatus is in networked communication with a fitness tracking computing system. The configuration and location of movable components of the exercise apparatus is determined based on sensors. This information is provided to the fitness tracking computing system via networked communication.

The present invention relates to an exercise apparatus. The exercise apparatus includes a platform with an endless belt. The endless belt defines an exercising space above it. A restricting device has a retaining portion, a left restricting portion and a right restricting portion. The two restricting portions are elongated and flexible, such as straps. The left restricting portion is connected to a left end of the retaining portion from a left rear of the exercising space. The right restricting portion is connected to a right end of the retaining portion from a right rear of the exercising space. The restricting device maintains the retaining portion at an appropriate position to make the retaining portion naturally abut against a waist of the user for resisting forward movement of the user toward a front side of the exercising space and allowing the user to sprint or quick run on the platform.

An exercise apparatus comprising: a weight stack, a flexible elongated cable having a downstream portion that is interconnected to a user selectable number of the one or more individual bodies of weight and to a second resistance device, a manually movable actuating device interconnected to a proximal end of the cable, a downstream portion of the cable being interconnected to the one or more individual bodies of weight and to the second resistance device in an arrangement that pulls on both the one or more individual bodies of weight and the second resistance device.

A multifunctional recumbent exercising device is disclosed, including a base frame, a first transmission unit, a first retracting unit, a resistance unit, a first guiding piece and a first movable seat. By changing a relative position between the first movable seat and the first guiding piece, the position of a first slide-assistance portion of the first movable seat on the base frame can be changed. The multifunctional recumbent exercising device allows an operator to apply force to a first side or a second side of the base frame, in order to select various kinds of training modes.
