Amud Yomi (Hebrew: עמוד יומי) "column [of the] day" or "daily page") is a daily regimen undertaken to study the Babylonian Talmud one amud each day.
Many have, however, found it difficult to keep up with the "heavy load" of two pages (or one daf) each day.
[1] As such, Amud Yomi was created as a mechanism allowing for the review of all of Talmud, systematically while at a manageable pace.
Most programs schedule some days for review or catch up, typically on Saturday and/or Sunday.
In some cases - such as at Etz Chaim Yeshiva (London) - this pace, relative to Daf Yomi, allows for the major mefarshim to be reviewed alongside the daf, and "shas" may then be completed with commentaries.
