Why are the programs changing to two sets/rounds?

The traditional high-volume format (e.g. 4 sets of 10–12 reps) has shifted instead to two high-effort working sets. Why? Because intensity is essential for maximizing progress.

When training to failure, you simply don’t need as many sets to stimulate growth. Each set listed within the program is a “working set” and designed to be all-out, where nothing is left in the tank. In contrast, with higher-volume programs, people often stop when the burn gets uncomfortable, but still have reps left. This update allows you to train harder, recover better, and see more progress.
