The present invention relates to forearm fitness equipment having a first handlebar and a second handlebar which are arranged in a longitudinal direction. The first handlebar includes a twist guide part and a first spiral inclined surface formed on an end surface of one side of the twist guide part. The second handle bar includes a second spiral inclined surface on an end surface, which comes into contact with the first spiral inclined surface. The first and second spiral inclined surfaces extend spirally respective in an opposite rotational direction to each other. A spring is configured to provide an elastic force in a direction in which the first spiral inclined surface and the second spiral inclined surface come into contact with each other.
