Abstract: A dual-turntable training device includes a base, two turntable units, and a resistance unit. Each turntable unit includes a rotating shaft, a turntable, and a grip. The rotating shaft is pivoted to the base. The turntable is secured to the rotating shaft. The two turntables of the two turntable units are horizontally arranged side by side. The grip is vertically disposed on the turntable. The resistance unit includes a control member and two resistance members. The control member is disposed on the base. The control member is connected to the two resistance members. The two resistance members correspond to the two turntables and are configured to apply rotation resistance to the two turntables. By operating the control member, the two resistance members are moved closer to or away from the two turntables for adjusting the rotation resistance.
