Progressive resistance training protocols must manipulate variables such as intensity, volume, and exercise selection to stimulate adaptation toward specific goals like strength, hypertrophy, or power.
To build strength or muscle, you must progressively challenge your body. Start with 8-12 reps per set. Once you can do 1-2 extra reps comfortably, increase the weight by 2-10%. Do 2-3 sets if you are new, but move to 3-4+ sets if you have been training for months. Prioritize compound movements like squats and presses.

In order to stimulate further adaptation toward specific training goals, progressive resistance training (RT) protocols are necessary.

- Periodization (systematic variation of volume and intensity) is superior to non-periodized training for maximizing long-term strength gains, particularly in trained individuals.Good
- Rest periods of 2-3 minutes are recommended for core exercises using heavier loads to maximize strength gains, whereas shorter rest periods (1-2 min) may suffice for assistance exercises.Good
