The bar does not tell the whole story
Imagine two sessions at the same weight: you complete eight repetitions in one and nine in the other, keeping the exercise and execution comparable. The load is unchanged, but the work performed is different. Progressive overload means gradually adjusting training demands as you adapt. It does not require adding plates on every gym visit or make a session without a record worthless.
What the research says
A trial by Plotkin and colleagues, published in PeerJ in 2022, compared increasing load with increasing repetitions over eight weeks of lower-body training. Forty-three trained participants were assigned to groups and 38 completed the study. Both strategies produced adaptations, with similar results for most muscle-thickness measurements. This was a short study in a specific population: it does not prove that every progression method is equivalent for every goal. ACSM’s 2026 evidence summary recommends matching load and volume to the goal and individual.
Keep a log that allows comparison
Our practical suggestion is to record the exercise, load, repetitions in each set and approximate rest. Add a brief note about execution and perceived effort. Fictional example: a row on the same machine with the same settings, 30 kg, sets of 10/10/9; another session gives 10/10/10 with comparable rest and range of motion. You can now identify what improved. Record changes in equipment, much shorter movement or twice as much rest: an isolated number lacks context.
Change something for a reason
Review several sessions before deciding. You might target more repetitions within a planned range or a modest load increase when it fits your plan; every variable need not change at once. The log supports discussion with a trainer and better decisions, rather than an automatic weekly increase. ACSM places consistency and individual adaptation above unnecessarily complex programmes. Keep information that helps you train better, not merely numbers that look impressive in a screenshot.
