Top Sets and Back-Off Sets
As the weights continue to increase, there comes a point where doing all 3 sets of 5 at the same weight reaches its limit.
For the squat, the next step can be to separate the heaviest work from the work that follows it. Instead of 3×5 across, you perform 1×5×100kg, followed by 2×5×90kg.
These lighter sets are your back-off sets, and they should stay approximately 10% below the top set. That separation matters. As the top set increases, the back-offs don’t necessarily need to increase with it and may stay at the same weight for a couple of sessions.
The light squat day is then calculated from the back-off sets rather than the top set.
The same approach can be used with the bench press. One top set of 5 is followed by back-off work at approximately 90%, allowing the heaviest work and the work that follows it to be loaded differently.
For women, the structure is slightly different. Squats can progress to two top sets of 3 followed by 3×3 back-offs, initially around 10% lighter. If those back-offs are too easy, the reduction can be closer to 7–8%. For the bench press, a smaller reduction of around 5–8% can be used.
The key idea is simple: not every work set has to be performed at the same weight. Top sets allow heavier weights to be handled, while back-off sets provide the work that follows at a lower load.
In Part 5, we’ll look at what happens when sets of 5 reach their limit and the program begins moving towards lower-rep work.
