Multifunctional fitness device

A multifunctional fitness device, wherein the multifunctional fitness device comprises a support mechanism and a chassis mechanism, the support mechanism is rotatably connected to the chassis mechanism;

• when the support mechanism rotates and is fixed to a first position on the chassis mechanism, a first angle is formed between the support mechanism and the chassis mechanism, and the support mechanism is configured to cooperate with the chassis mechanism, such that the multifunctional fitness device is in a running mode;
• when the support mechanism rotates and is fixed to a second position on the chassis mechanism, a second angle is formed between the support mechanism and the chassis mechanism, and a supporting member in sliding connection with the support mechanism is configured to cooperate with the support mechanism, such that the multifunctional fitness device is in an abdominal workout mode, wherein the second position is located between the first position and the chassis mechanism;
• and
• when the support mechanism rotates and is fixed to a third position on the chassis mechanism, a third angle is formed between the support mechanism and the chassis mechanism, and a stretch member arranged on the support mechanism is configured to cooperate with the supporting member and the support mechanism, such that the multifunctional fitness device is in a rowing mode, wherein the third position is located between the second position and the chassis mechanism.
