The invention discloses a stepping type body relaxing device which aims at overcoming the defects that an existing training device cannot effectively relieve the diseases and pains of the waist, and the brain is likely to be vibrated excessively to be damaged. According to the technical scheme, when a power assembly works, a driving wheel drives a driven wheel to rotate through a transmission belt to drive a rotating shaft to rotate, and thus a cam can rotate around the rotating shaft. When the bottom faces of pedals abut against a first arc edge, the pedals are gradually ejected upwards to the highest point by the first arc edge along the rotation of the cam; when the bottom faces of the pedals leave the first arc edge, the pedals conduct the free-fall motion until the bottom faces of the pedals abut against a second arc edge, and the pedals achieve the repeated perpendicular lifting motion along with the rotation of the cam around the rotating shaft. The stepping type body relaxing device has the advantages that the muscle of the waist is fully exercised and effectively relaxed, waist diseases such as lumber muscle strain and chronic lumbago and backache are relieved, the effect of relaxing the body is achieved, and the damage of the brain due to excessive vibration in the moving process can be avoided.
