The new ACSM resistance-training guidelines, the first update in 17 years, say training to momentary failure is more optional than people think. Stopping a rep or two short works about the same for strength, size, and power. What matters is how much you do, and how hard.

![Does Training Frequency Matter for Strength and Size?
If you have three lifts planned for the day but split them hours apart, are you leaving strength and size on the table? The short answer from Jordan and Dr. Austin Baraki: it is fine. The longer answer is a useful window into how they think about programming.
Frequency is a tool to distribute training load, not an independent driver of adaptation. When you equate volume, the frequency signal mostly disappears: Schoenfeld’s 2016 meta-analysis showed a small hypertrophy edge for higher frequency, but the volume was not actually equated, and the 2019 update with 25 studies erased the difference. Strength data tell the same story. Where Jordan goes slightly beyond the evidence: he suspects splitting volume up lets you accumulate more total training load over months and years because you lift fresher, and that higher-skill lifts like the overhead press may benefit from frequent, low-fatigue exposure.
They extend the same logic to cardiorespiratory fitness, where the old 10-minute bout minimum has been dropped entirely, while still arguing that some longer sessions matter if maximizing fitness is the goal. The practical takeaway: distribute your training by preference and logistics, prioritize adherence, and do not worry that splitting a session hurts your results.
