Lever / hammer machines domestic or for semi-professional use. Lever machines do not carry a plate tower and are loaded with weight discs. They are a very effective way to gain strength and muscle mass at home.
Bodybuilding machines classified as domestic: they are only recommended for individual / family use at home.
The bodybuilding machines classified as semi-professional: they can be valid for training at home and for small / medium gyms where they will not be given a very excessive use. Although they can be installed in a commercial gym , they would lose their warranty, as they are not 100% professional material.
