The Rebbe encouraged his talmidim to study all four sections of the Shulchan Arukh systematically, with all the nosei keilim. However, if this is not possible, one should learn the Shulchan Arukh (Mechaber and RaMA) with minimal commentary. In any event, one should learn at least one halakhah per day, even if it is not part of one’s regular seder ha-limud. The Baal Shem Tov similarly stressed the regular study of halakhah le-ma’aseh.
