Beyond Rep Ranges: How to Gauge Your Training Intensity for Better Results

According to an MSN item on optimizing rep ranges for strength and muscle growth, the familiar training-room question is back on the table: when a set feels hard, how do we know whether it is building strength, muscle, or simply leaving us sore? The available source material does not provide a specific rep prescription, and that restraint matters. For recreational athletes, the useful starting point is not chasing one “correct” number, but learning how a chosen training dose is landing in the body.

Rep ranges are only part of the training signal

“Rep range” is a tidy label for something that is rarely tidy in practice. Two sets with the same number of repetitions can create very different experiences depending on the exercise, the overall load, and the athlete in front of it. If we are trying to improve strength or muscle growth, it is tempting to treat the number on the program as the whole decision. It is not.

What we can take from this week’s discussion is a more practical question: can you repeat the movement with good enough control, and can the joint and surrounding tissue tolerate the training dose over time? That is movement literacy in its useful form—not overanalysing every sensation, but noticing patterns.

A rep target can give structure to a session. It cannot, by itself, tell us whether the exercise choice, load, timing, or accumulated fatigue fits the athlete’s current capacity. When the same workout repeatedly leaves a movement feeling less coordinated or harder to return to, that is information worth keeping in the plan.

Soreness is not a simple damage report

A new review in Frontiers in Sports and Active Living offers an important bit of context for anyone using soreness as their training scorecard. The authors describe delayed-onset muscle soreness, or DOMS, as a multifactorial neurophysiological response rather than a straightforward measure of muscle damage.

That language may sound technical, but the translation is reassuring: a sore muscle does not deliver a simple verdict on whether training was effective or excessive. The review describes overlapping inflammatory, neural, metabolic and proprioceptive pathways across endurance, resistance and plyometric exercise. In other words, the body’s response reflects more than one system, and different forms of exercise can produce different patterns.

For resistance training, the review notes an association with Group III/IV nociceptor activation and strength loss; plyometric work is described in relation to proprioceptive disruption and C-fibre sensitisation. We do not need to turn that into a diagnosis after a hard session. But it does reinforce a useful habit: listen to the joint, the movement, and your ability to produce force—not soreness alone.

Match recovery to the work you actually did

The review’s central practical point is that recovery strategies should be exercise-specific. It reports that compression garments, acupuncture and foam rolling reduced DOMS severity in the studies reviewed, while also stressing that responses depended on exercise modality, load, timing and individual neurophysiology. There is no single recovery ritual that answers every hard session.

That fits the broader question around repetitions. A lower- or higher-repetition choice is not meaningful in isolation if its recovery cost is ignored. After an unfamiliar resistance session, a demanding endurance effort, or repeated jumping, the next training decision should account for how your body is functioning—not merely whether the plan says it is time to add more.

National Geographic has also raised the adjacent question of when exercise stops making us stronger and begins causing damage. The available material here does not supply a clean boundary, and real training rarely does. The more durable approach is to let repetition targets guide practice while keeping an eye on tolerance: how the movement feels, how performance returns, and whether the next exposure can be completed with the same calm control.
