MAKING
TENSION COUNT

In short: Good tension in the stretch is the foundation. Three things turn it into growth: feeling the muscle work, choosing exercises that give a lot without draining you, and training close enough to failure.

1.Feel the muscle work

Tension is not just about the weight — it is about producing a strong, deliberate contraction in the muscle you want to grow. Feel the target muscle work on every rep. Do not just move the load from A to B.

This matters because no two bodies are built the same. An exercise that works brilliantly for one person may barely register for another. There is no single best exercise for everyone.

So early on, experiment. Try different movements for each muscle and notice which ones give you a strong, clear contraction in the right place. Those are your exercises — and finding them early saves you months of training movements that were never going to work for your body.

2.Give a lot, take a little

Every exercise gives you two things: a stimulus (the growth signal you want) and fatigue (the tiredness you have to recover from). The best exercises deliver a strong stimulus for as little fatigue as possible. This is the stimulus-to-fatigue ratio.

It matters because recovery is limited. An exercise that leaves you drained costs you time, food, and rest — resources you could have spent growing. One that gives nearly the same signal while leaving you fresher is simply a better deal.

Prioritise these high-value exercises: you get the signal you need, recover faster, and train again sooner. More growth, less cost.

3.Train close to failure

You can grow across many rep ranges — heavy and low, or light and high. But one thing is always true: the set must come close to failure to signal growth.

Failure is the point where you cannot complete another good rep. Stop far short of it, with easy reps still in the tank, and the signal is too weak — however many reps you did. The last few hard reps are what tell the muscle to grow.

You do not have to reach failure every time. Stopping one to two reps short produces similar growth (Refalo et al., 2024), while leaving you less drained — which ties straight back to the stimulus-to-fatigue idea above.

Judging how close you are is a skill. It feels vague at first, but sharpens with experience. There are also reliable physical signs that a set is genuinely close to failure — and those are exactly what the next article covers.

You now know how to produce good tension, feel it in the right muscle, choose efficient exercises, and train hard enough. The last foundational skill is reading your own sets — the visible signs that a set was close enough to count.
