The rep range on your plan — say 10–15 — isn't just a number. It's a diagnostic tool. It tells you exactly whether your weight is right.

The rule: Volume overload first — add reps until you can comfortably do the top of your range (e.g. 15). Then add weight, drop back to the bottom of the range (e.g. 10), and build back up. This is the loop that produces consistent, injury-free progress.

Your body adapts to stress. If the stress stays the same, the adaptation stops. Progressive overload means you give your body slightly more work to do — week after week. Not dramatically more. Just more.

Use your volume tracker. The tracker built into every session shows your sets, total reps, and estimated volume in kg. Your job week on week is to make that number go up — even by a tiny amount. That's progress.

Volume is the total amount of work you do. Not just how heavy — how much. 3 sets of 12 at 40kg = 1,440kg of total volume. Track it. If your volume is going up week on week, you're progressing — even if the weight doesn't feel heavier yet.

Don't try to do everything at once. Four weeks of consistent moderate volume beats two weeks of extreme volume followed by injury and time off. Build slowly. Stay consistent.

RPE is a scale from 1–10 describing how close to failure you are. Most of your working sets should sit at RPE 7–8 — meaning you could do 2–3 more reps if you really had to, but you chose to stop.

Going to RPE 10 (failure) on every set isn't productive — it destroys recovery and increases injury risk. Train hard. Not recklessly. Aim for RPE 7–8 on most sets, occasionally 9 on your last set of an exercise.

If you rest too little, you haven't recovered enough to produce the same output next set — so your reps drop, your weight drops, and your volume drops. You get the feeling of a hard workout with less actual stimulus. Rest properly.

A drop set is when you take a set close to failure, then immediately reduce the weight by 20–30% and continue repping without resting. You're extending the effective work of that set beyond what you could do at the original weight.

When to use: Last set only of an isolation exercise (curls, raises, extensions). Don't drop set compound movements — too much systemic fatigue. 1–2 drop sets per session maximum during these 4 weeks.

A rest-pause set takes you close to failure, pauses briefly (10–15 seconds — just enough to partially recover), then continues for a few more reps at the same weight. The weight doesn't change; only the rest does.

Best for: Machine exercises and isolation movements where you can safely stop mid-set. Excellent on the last working set of any isolation exercise. Like drop sets — don't overuse. One or two per session.

Never go straight to your working weight on the first exercise of a session. Warm-up sets prime the movement pattern, lubricate the joints, and signal your nervous system to recruit the right muscles. They are not junk volume — they make your working sets better.
