The gym I train at – Ironsport Club – has the best training machines I've ever used. They are of the German brand Sygnum (and again, the Germans have proved that they are the best in the world to build machines of high quality).
These machines are very solid and biomechanically designed in such a smart way that makes you get great muscle contact. You simply get a new dimension to your workout!
Usually, I am an advocate of free weights but as a complement some machines can be great tools for shaping your body.
