Fitness training aid

Abstract

A fitness training aid including a flexible, impermeable membrane defining a chamber fillable at least in part with a first flowable material and at least in part with a second flowable material, at least closure coupled to the membrane, at least one gripping member coupled to the membrane, and at least one wall positioned within the chamber. The closure positionable between at least one open position enabling the first and / or second flowable materials to be introduced within the chamber, and a closed position that seals the first and / or second flowable materials within the chamber. The at least one wall and the membrane define at least first and second compartments within the membrane. The at least one wall enables fluid communication of the first and / or second flowable materials between the first and second compartments.

Description

RELATED U.S. APPLICATION DATA[0001]The present application claims priority under 35 U.S.C. §119 to Italian Patent Application No. MI2015A000501 filed on Apr. 8, 2015.FIELD OF THE INVENTION[0002]The invention relates to a fitness training aid, and in particular to an aid comprising a mass to be lifted and gripped to enable training exercises to be performed.BACKGROUND OF THE INVENTION[0003]Various types of fitness training aids are known, such as kettlebells, dumb-bells, weight bars or similar. These known aids, which allow users to perform a multitude of exercises to train different muscles of the body, have intrinsic limitations, however, due to their shape. In particular, these aids generally comprise a rigid or substantially rigid body, with a center of gravity that is fixed with respect to the geometry of the body. The load of these aids is therefore described as stable.[0004]In some training contexts, both at competitive and non-competitive level, and for rehabilitation, it is ...

AI Technical Summary

Benefits of technology

The present invention provides a training aid that can create an unstable load that is controlled at least in part and can adjust the degree of instability based on movements in different directions. The aid can also change the total load in a simple and practical manner. The design is economical and easy to make. The aid includes a chamber with at least two compartments in fluid communication with each other and a partial wall to regulate the flow of liquid between the compartments, limiting the impact force on the person performing the exercise. In some cases, the aid may have additional non-contact zones where the liquid can flow. Reinforcing strips may be added to the membrane to increase its flexibility and prevent deformation.

Problems solved by technology

These known aids, which allow users to perform a multitude of exercises to train different muscles of the body, have intrinsic limitations, however, due to their shape.

The movement of the liquid therefore generates a continuous variation in the aid's center of gravity that is often sudden and not foreseeable by the athlete.

However, this aid does not make it possible to control the movement of the liquid inside the bag, for example between opposing walls.

When performing rapid movements, the excessively fast movement of the liquid can generate recoil due to the inertia generated by the impact of the liquid against the internal walls of the bag.

However, the use of different fillers, particularly if they are not liquids, may be impractical for some users or applications when one considers how different users, for example in a gym, may want to choose the load and type of instability they want in the aid before performing the exercise.
