02: Reps Done vs. Reps Left — And Why It Matters

If you're consistently landing on even numbers or 10 reps for your sets, you might be stalling your progress. And in this episode, I explain why.

Most strength programs give you tidy rep prescription, such as to do 3 sets of 10. But when 10 becomes the thing you chase, it’s easy to lose sight of the variable that actually drives progress.

In this episode, I break down why reps and load are not the primary drivers of strength, why effort at the end of the set is what truly signals change, how to use reps in reserve, and how to spot a subtle clue in your training log that **might** mean you’re under-efforting.
