The invention discloses a body-building tricycle driven by hands and feet. The body-building tricycle is characterized by comprising two front wheels, a back wheel, a driving part and a transmission part, wherein the driving part produces driving power via user hands and feet; the transmission part can transmit the driving power to the wheels; the driving part is formed by a rocking arm and pedal plates held by hands and stepped by feet; the rocking arm and the pedal plates can swing back and forth via user hand and foot movements, so driving power can be produced; the transmission part is formed by a rocking arm gear connected to the rocking arm and a pedal gear connected to the pedal plates; the rocking arm gear is engaged with the pedal gear; and the rocking arm gear and the pedal gear respectively rotate back and forth and transmit the driving power to the back wheel. The body-building tricycle is driven by hands and feet at the same time, so driving torque can be increased by times compared to a traditional bicycle single-foot driving way; the user can drive fast with less effort; the user can move all over the body and the upper limbs and the belly part can be especially exercised; and the body-building tricycle can work as a preferential instrument for outdoor exercise.
