How close to failure should you train?

A recent meta-analysis has shaken up the fitness community by concluding that you should train pretty much to failure every set. That seems to be the conclusion. If you read the results at face value. And this has also led to a resurgence of the effective reps model. So in this video, I'd like to cover that meta-analysis, the science of how close to failure you should train, and also go into associated terms like junk volume. *Chapters* 00:00 Introduction 00:26 Effective reps model 03:33 Greg Nuckols's critique 04:19 Paul Carter's response to Greg's critique 07:22 New meta-analysis 13:33 Why are these results odd? 16:44 Previous meta - Refalo et al. 18:47 Why is the effective reps model flawed? 22:53 Two previous meta-analysis - Vieria et al., Grgic et al. 24:30 Studies on the topic - Martorelli et al., Da Silva et al. 26:02 Conclusion - does volume matter? 29:11 Outro *References* The Chris Beardsley effective reps model: https://sandcresearch.medium.com/what-is-training-volume-286b8da6f427 Greg Nuckols’ critique: https://www.strongerbyscience.com/effective-reps/ New meta: https://www.researchgate.net/publication/370837310_Exploring_the_Dose-Response_Relationship_Between_Estimated_Resistance_Training_Proximity_to_Failure_Strength_Gain_and_Muscle_Hypertrophy_A_Series_of_Meta-Regressions Refalo et al.: https://link.springer.com/article/10.1007/s40279-022-01784-y A motor unit-based model of muscle fatigue: https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1005581#pcbi-1005581-g003 Muscle fiber activation study: https://onlinelibrary.wiley.com/doi/abs/10.1111/apha.13302 Individual responses for muscle activation: https://www.mdpi.com/2075-4663/3/4/269/htm Vieria et al. meta: https://pubmed.ncbi.nlm.nih.gov/33555822/ Grgic et al. meta: https://www.sciencedirect.com/science/article/pii/S2095254621000077 Martorelli et al. study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5505097/ Da Silva et al. study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5505097/ - Check out my free email course for my most popular content: https://mennohenselmans.com/subscribe #mennohenseelmans #trainingtofailure #exercisescience #bodybuilding #hypertrophytraining #trainingvideos #exercisescientist #strengthtraining #strengthandconditioning
