Another spinoff of Bill Starr’s 5×5, Madcow 5×5 incorporates bodybuilder-friendly assistance work (along with lots of rows) with the fundamental Big 3 compound movements to create a simple but effective strength program. Though originally designed with bodybuilding in mind, this can be effectively utilized for off-season (read: not peaking) powerlifting training, as the linear progression and rep range complement strength gains nicely.
The advanced periodization version is also included, which is referred to as “StrongLifts Advanced” even though it’s really Madcow advanced. It is similar to Madcow intermediate, but increases the average tonnage (sets*reps*weight) of each week and includes a deload in the middle of the program.
