Upper-body pump work can often return to the next set quickly, but small muscles and shoulder mechanics still need clean execution.

Begin with enough room

Start at an interval that allows every planned set to match its range and target. The first rung is a baseline, not a test of toughness.

After consistent completion, reduce rest in a small step and hold it until the new rhythm feels owned.

Watch assistance creep

As rest shortens, traps can take over raises, shoulders can dominate presses, and momentum can enter curls. Those are signals to hold or restore the interval.

Density only counts when the intended muscle keeps the work.
