tuesday: chest + calves ( dips and inc bench indirect for shoulders and tris )
wednesday: rest
thursday: back + abs ( chins and rows indirect for biceps )
friday: shoulders + tris ( cg bench indirect for chest )
sat/sun: off

here's the routine:

3x10, 2x10, 4x8, 2x8, 3x6, 2x6, 4x4, 2x4. Work hard, then back off
