Features: The rowing machine mainly exercises the muscles of legs, waist, upper limbs, chest and back, as well as the muscle strength and endurance training of lumbodorsal muscles, upper limb flexors and lower limb extensors. Rowing machine, also known as rowing machine, is a kind of simulated rowing equipment. It has a good effect on strengthening the muscles of legs, waist, upper limbs, chest and back, especially on the muscles of arms, back and abdomen. When rowing, every flexion and extension of the arm can exercise about 90% of the extensors.Therefore, it is beneficial to the extensors who hardly participate in any exercise at ordinary times. At the same time, it also has obvious effect on the exercise of back muscles, which can make the back have a larger range of motion in the body flexion and extension, so that the various joints of the spine can be exercised. This can not only improve the elasticity of muscles, but also enhance their toughness.
