Periodization (systematic variation of volume and intensity) is superior to non-periodized training for maximizing long-term strength gains, particularly in trained individuals.

If you have been training for more than 6 months, stop doing the same weights and reps every week. Use a periodized plan that alternates between higher reps/lower weight and lower reps/higher weight. This keeps your body adapting and prevents plateaus.
