Not all weights, some of them are glued to the shelf for decoration. Oh, I see now, that was 17 kg in ONE piece. And over there, 46. I lift it by two millimeters, for one second, with two hands, and laugh.
Come to think of it, the equipment around looks so technical it is like an (office coloured) torture chamber mixed with the outside of a particle accelerator.
But I do well. My third time and I am using many muscles, quite enjoy some challenging movements and I work out constantly for one hour. I wouldn't without a friend, who introduced me to some moves and the relaxed attitude to lifting. Now I am going to pass on the favour next Thursday.
