1. A system (S) for monitoring a weight adjustment of a dumbbell, which can be used by a user to perform a gymnastic exercise, the system comprising:
a dumbbell (2) provided with
a handle (21) having an axial development along an axis (R), able to rotate around said axis (R), clockwise and counterclockwise, and provided with a first end (211) and a second end (212),
a first plurality of weights (P1), wherein each weight can be individually coupled to said first end (211), when said handle (21) rotates in one direction, and decoupled from said first end (211), when said handle (21) rotates in the opposite direction, and
a second plurality of weights (P2), wherein each weight can be individually coupled to said second end (212), when said handle (21) rotates in one direction, and decoupled from said second end (212), when said handle (21) rotates in the opposite direction,
wherein said system (S) is characterized
in that it comprises an element provided with a plurality of reflective portions (321a, b, . . . , n),
in that it comprises at least one detection device (5) able to detect data coming from at least one reflective portion (321k) and able to send said data,
in that it comprises a logic control unit (U) able to receive said data sent by said at least one detection device (5) and to associate with said data a weight of said first (P1) and second (P2) plurality of weights,
in that said detection device (5) comprises at least one sensor (51), able to emit electromagnetic waves and receive electromagnetic waves reflected from at least one portion of said plurality of reflective portions (321a, b, . . . , n), and
in that said at least one sensor (51) is arranged in said first end (211) and/or in said second end (212) of said handle (21).
