## Abstract

Disclosed is an exercise device including flexible suspension unit, a mass, a fastening element and optionally a separate grip, wherein: a) the flexible suspension unit, elongated and thin in shape, are connectable at the level of at least a first end to the fastening element and at the level of an opposite end to one of such components; b) the mass has a through hole through which the suspension unit passes, the through hole being provided with a first opening and a second opening; and c) the fastening element can be blocked on the body of the mass.

## Claims

### Claim 1

An exercise device (1) comprising:
flexible suspension means (3) elongated, the flexible suspension means (3) being thin in shape and made of an elastic material;
a mass (4) having a body; and
a fastening element (5) that can be blocked on the mass (4),
the mass (4) has a through hole (6) through which said flexible suspension means (3) pass, said through hole (6) being provided with a first opening (8) and a second opening (9),
wherein the fastening element (5) comprises a hollow piece (10) that can be inserted in said through hole (6) and that is provided therein with at least one cavity (12) in which at least one portion of a part of the flexible suspension means (3) inserted into the through hole (6) is housed,
wherein the fastening element (5) is separable into two parts (5′, 5″) with respect to a plane parallel to a major axis of the fastening element (5), and
wherein the flexible suspension means (3) comprises a single element bent and having a first end (3a) and a second end (3b), each of the first and second ends (3a, 3b) being fastened in the at least one cavity (12) of the fastening element (5).

### Claim 2 (depends on 1)

The exercise device (1) according to claim 1, wherein at least an end of the hollow piece is provided with an abutment element (11) that abuts against an area surrounding at least one of said first and second openings (8, 9) of the body of the mass (4).

### Claim 3 (depends on 1)

The exercise device (1) according to claim 1, wherein the flexible suspension means (3) have, at a level of or close to at least one of the first and second ends (3a, 3b), a blocking element (7) adapted to constrain the flexible suspension means (3) to the fastening element (5).

### Claim 4 (depends on 3)

The exercise device (1) according to claim 3, wherein the flexible suspension means (3), at least close to or at a level of the first end (3a), are hollow so as to house the blocking element (7).

### Claim 5 (depends on 4)

The exercise device (1) according to claim 4, wherein the blocking element (7) is a ball.

### Claim 6 (depends on 1)

The exercise device (1) according to claim 1, wherein the flexible suspension means are provided with a slider (18) that delimits a portion of the suspension means that acts as a grip.

### Claim 7 (depends on 1)

The exercise device (1) according to claim 1, wherein the flexible suspension means (3) are bent in a U-shape and wherein the at least one cavity (12) of the fastening element (5) has at least two seats (12′, 12″), each of the at least two seats housing one of the first and second ends (3a, 3b) of the flexible suspension means (3) bent in a U-shape, and separated by a dividing wall (19) that extends along a direction substantially parallel to ire a major axis of the fastening element (5).

### Claim 8 (depends on 7)

The exercise device (1) according to claim 7, wherein the flexible suspension means (3) have, at a level of or close to at least one of the first and second ends (3a, 3b), a blocking element (7) adapted to constrain the suspension means (3) to the fastening element (5), and in which the dividing wall creates at least one narrowing in the at least two seats (12′, 12″) to prevent sliding of the blocking element (7).

### Claim 9 (depends on 1)

The exercise device (1) according to claim 1, wherein the mass (4) is a spheroid body.
