Without knowing the set and rep scheme and what your future goals are, my personal view (just my own opinion, who really cares anyway) is that it is one of the worse workout plans I have come across in a long time. You have a PR at home, which is one of the most useful ways to pack on muscle size and strength. Wonder if you though of making full use of it? Of course if your training for a sport that may require keeping the body somewhat in shape during a playing season, than maybe.
Might find, with a well planned 3 or 4 day a week lifting plan, using a PR and interchanging pin positions, size and strength gain can come rather fast for you. If your on some heavy cycle chemical stuff than you might get away with that program you had listed. Any way, Good Luck.
