The invention discloses a strength-adjustable arm training
machine, and relates to the technical field of physical training instruments.The strength-adjustable arm training
machine comprises a base and a supporting frame, a plurality of balancing weights are slidably connected into the base, an
insertion rod is inserted into each balancing weight, and two ropes are symmetrically and fixedly connected to the upper surface of the uppermost balancing weight; two ropes are arranged on the base, one end, penetrating through the supporting frame, of each
rope is fixedly connected with a hand pull ring, a training mode adjusting
assembly is arranged on the base, and the training mode adjusting
assembly comprises two strip-shaped grooves symmetrically formed in the base. The problems that a traditional pull-down arm training instrument can only do pull-down actions and can mainly exercise latissimus dorsi muscles,
biceps muscles and the like, but horizontal pulling and lifting can involve different
muscle groups, for example, deltoid muscles and trapezius muscles can be exercised through horizontal pulling, shoulder muscles and triceps muscles can be exercised through lifting, more
arm muscle groups can be covered for training, and the limitation of single training is avoided.
