As we approach muscular failure, muscle fibre recruitment goes up. This stimulates the motor units that contain the majority of the large, highly-responsive fibres to grow. So in simple terms, the idea is that the last 5ish reps before failure are “stimulatory reps” because they involve both full motor unit recruitment and a high level of tension.

But recent research indicates training to failure is not necessary. So should you train to failure? Are 'effective reps' a crock of shit?

Listen in and I'll give you my take.
