| Add load | Increase the weight on the bar or machine while keeping reps and form the same. | The most direct method, but you cannot add load every week forever - small jumps beat big ones. |
| Add reps | Keep the weight and add reps to a set - 8 reps this week, 9 or 10 next - then add load once the top of the range is hit. | Ideal when a weight jump would break form; double progression pairs reps then load. |
| Add sets | Add a working set to a movement to raise total training volume for that muscle. | Powerful early on, but volume cannot climb indefinitely without recovery catching up. |
| Add frequency | Train a muscle or lift more often across the week so more quality sets accumulate. | Useful when a single session cannot hold more volume without fatigue tanking quality. |
| Add density | Do the same work in less time by trimming rest, so each session packs more in. | Good for conditioning and time-pressed clients; less suited to top-end strength. |
| Improve range of motion or control | Deepen the range, slow the lowering phase, or clean up technique on the same weight. | Quality progress that does not show on the bar but still raises the demand. |
