The baseline
Repeat enough to create a comparison.
Progress is difficult to interpret when the movement, repetition target, rest time, and effort all change at once. Keep the main exercise and its basic conditions stable long enough to compare one session with the next.
The ACSM review supports progressive resistance training, but it does not make constant exercise novelty a requirement. A stable movement gives you a place to apply progression.

The change
Move one lever at a time.
Useful progression can come from adding a repetition, adding a small amount of load, increasing range of motion, improving control, or choosing a more demanding variation. These changes do not need to happen together.
When you complete the planned work with repeatable technique and the intended effort for more than one session, choose the smallest change that keeps the exercise useful. If the change disrupts the movement, return to the prior version and build more practice.

The effort
Train hard enough without turning the set into a verdict.
A productive set can be challenging without becoming an all-out test. The 2026 ACSM synthesis did not find consistent outcome advantages from training to momentary failure across the evidence it reviewed.
Use a planned effort that leaves technique recognizable. Save maximum-effort testing for a purpose that actually requires it, not as the default way to prove that a workout worked.

The filter
Add complexity only when it solves a named problem.
The ACSM update emphasizes that consistency, individual goals, safety, enjoyment, and sustainability matter more than a needlessly complicated plan. Equipment type, complex periodization, and several advanced techniques did not consistently determine outcomes in the review.
Complexity can still be useful for a specific performance goal, a long training history, or a scheduling problem. It should arrive with a reason and an observable job.
