The invention relates to a fitness device which intelligently controls the training intensity, including: a fitness device； a control unit which signals the fitness device； and a communication unit which signals the control unit； the communication unit obtains a pre stored message according to which the control unit limits the training intensity range of the fitness device.In this way, the user's overload or insufficiency caused by too much or too little training intensity can be avoided, so as to make the training result of a user inconsistent with the expectation, and even cause the user's sports injury.本創作係有關於一種智慧控制訓練強度的健身裝置，包含：一健身裝置；一控制單元，訊號連接該健身裝置；以及一通訊單元，訊號連接該控制單元；該通訊單元取得一預存訊息，該控制單元依據該預存訊息限制該健身裝置的一訓練強度範圍。藉此，避免過大或過小的訓練強度造成使用者負荷過大或不足，以致於讓一使用者的訓練結果與預期不符，甚至造成該使用者的運動傷害。
