An off-lift day. Did 5x 3minute rounds with the heavy bag. In between rounds, medicine ball incline situps. Each set I did 4x S L O W crunches, then another 4x slow twists for obliques, then fast situps/throw and catch with the 14# ball. 5 sets total.
Good explosive stuff for lean muscle, I hope. If you think about it, Rocky's training and diet was all about Evolutionary Fitness: right down to the glass of raw eggs!
