A system for measuring vertical jump is disclosed, in accordance with one or more embodiments of the present disclosure. The system may include a vane assembly comprising a plurality of vanes movably coupled to an extendable member at a plurality of heights relative to a ground level, each being vane displaceable from an original position to a displaced position in response to contact from a user. The system may also include a measurement device configured to obtain at least one of: a baseline height from a first vane of the plurality of vanes to the ground level; a user height; a user reach; or a displacement height, wherein the displacement height is the height of the uppermost vane in a displaced position relative to the ground level. The system may also include a controller communicatively coupled to the measurement device.

Portable modular training systems are described herein. In one aspect, a modular training system includes a system container including a container front, a container rear, a container first side, a container second side, a container bottom, and a container top, defining a container cavity, and an exercise structure comprising a platform connector with a vertical support bar coupled to an interior surface of the system container and a horizontal bar coupled to the vertical support bar and extending external to the system container via an aperture defined by the system container.

Example embodiments may relate to a system, method, apparatus, and computer readable media configured for prompting a user to perform an exercise, monitoring form of the user while performing the exercise, and calculating an energy expenditure estimate for the user performing the exercise based on a type of the exercise and on the form of the user.

A frame structure for a mini trampoline includes at least three nodes and at least three elongate internodes, as well as a multiplicity of legs. In each case, two of the internodes are assigned to each other with end portions and are connected rigidly to each other via one of the nodes such that a closed frame lying substantially in one main plane is formed. Each leg is fastened directly to one of the nodes.

A pole vault swing-up rack includes a frame body with upper hooks and a lower push bracket. The rack is designed to hang vertically from a horizontal bar—as a pull-up bar—by the hooks. An athlete hanging from the pull-up bar in an upright vertical position may kick his/her legs and torso up to an inverted vertical position to simulate movement of a pole vault. The athlete's shoulders rest against vertical uprights of the rack to maintain the athlete's shoulders and body in front of a vertical plane as in a pole vault movement. A trainer can use the lower push bracket to assist the athlete in the kicking motion. The parts of the rack that come into contact with the athlete may be covered in foam padding and a rubber coating.

A modular resistance force system includes an axle configured to be rotatable around a rotational axis and one or more resistance mechanisms. Each of the one or more resistance mechanisms includes a resistance element disposed about a portion of the axle, a resistance element housing configured to house the resistance element and a resistance substance disposed between the resistance element and the resistance element housing. Either the resistance element or the resistance element housing is selectively engaged to rotate with the axle. A resistance between the resistance element and the resistance substance causes a force to be applied to the axle when the resistance element and the resistance element housing move relative to each other.

The invention comprises a plurality of indicator members rotatably coupled to an inner slide assembly, the inner slide assembly coupled to an inner channel member, the inner channel member further coupled to an outer channel member. In this configuration, system is mounted to a mounting surface through the outer channel member, the inner channel member is configured in a first state to freely traverse along a vertical axis of the outer channel member and in configured in a second state fixed at a single point on the vertical axis, and inner slide assembly is configured in a first state to freely traverse along a vertical axis of the inner channel member and in a second state fixed at a single point on the vertical axis.
