Example travel exercise equipment includes a barbell including a first end portion and a second end portion and a pair of yokes. Each yoke includes a base and a pair spaced-apart yoke arms extending from the base. The bases being adapted to be coupled to a corresponding end portion of the barbell. The travel exercise equipment includes a pair of containers having handles adapted to be carried by a corresponding yoke.

The invention relates to sports apparatuses with unstable surface intended for improving and maintaining ones physical condition. The sports apparatus according to a first embodiment comprises a flexible shell formed as a hermetic chamber with a valve and having an inner space for filling with a filler material and/or air. The hermetic chamber is accommodated within a case with handles. Once the chamber inner space is filled with a filler material and/or air, the sports apparatus in fact forms a rectangular parallelepiped with rounded corners. Side faces of the apparatus form a closed surface. The side face has a height not exceeding a half of the apparatus length. A supporting portion of the apparatus and a portion that the user interacts with are arranged to be identical and outwardly convex. The sports apparatus in operating condition has an elliptical cross-section. Said sports apparatus portions are unstable surfaces.

The inventive concept presented is a fitness training system featuring a plurality of different-sized containers having a detachable, water-tight sealing cap by which each container may be filled with a determinable quantity of a liquid, constituting a specific volume. The volume of the inserted liquid equates to a weight in pounds, facilitating the use of each container for exercise and fitness training. In the preferred embodiment, the liquid utilized is ordinary tap water. In this manner, a user may choose from a selection of variously-dimensioned containers, and proceed to fill an appropriate volume of water for creating the desired weight of one or more containers. By use of a handle grip and a handle stabilizer attached to the exterior surface of each container, the user exercises and strengthens a particular muscle or grouping of muscles, including the associated stabilizer muscles.

Disclosed is a kettlebell type apparatus for gymnastics including: a substantially spherical shaped body formed by a single flexible layer made of polymer material which defines an inner cavity: and a rigid handle fixed to the upper part of the body. The cavity is filled with a filling material that includes at least one liquid, where the filling material occupies from 10% to 80% of the volume of the cavity, and in which the body includes at least one sealable mouth for introducing the filling material into the cavity.

Disclosed is a workout backpack that is capable of enabling a plurality of unique exercises for weight training, resistance training, and complete cardio conditioning. Suitably, the disclosed workout backpack includes built-in weight compartments, hookups for resistance bands, or rucking.

In one aspect, the invention features a barbell including a first end portion, a second end portion, and a middle portion, where the middle portion is couplable to the first end portion and the second end portion. The middle portion includes a male coupling extending from a first end of the middle portion, the male coupling providing a first coupling mechanism that engages with a corresponding female coupling of the first end portion, and a female coupling providing a second coupling mechanism that engages with a corresponding male coupling of the second end portion.

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 portable aquatic exercise device for performing callisthenic workouts using water weight includes an outer bag having an outer surface and an inner surface wherein the inner surface of the outer bag creates an interior. The outer bag has a top end and a bottom end. The top end has an aperture and the bottom end has an opening. The opening has a draw string positioning the opening from an open position to a closed position. A pair of ropes is coupled to the outer surface of the outer bag. An inner bag is positioned within the interior of the outer bag. An inside of the inner bag is fills with water wherein expanding against the outer bag. A hole of the inner bag has an insert. A cap is positioned on the aperture of the outer bag and engages by threading to the insert of the inner bag.
