Stop choosing between strength and stamina and start building a high-performance body that can do both. Start training with intent today: citizenathletics.com
The "interference effect" has long been used as a scare tactic to suggest that cardio will inevitably kill your gains, but the modern science tells a much more nuanced story. While the molecular pathways for building muscle (mTOR) and improving endurance (AMPK) can technically blunt one another, for the vast majority of athletes, the real bottleneck isn't cellular, it's fatigue management. By understanding how to strategically time your sessions and manage training volume, you can successfully build elite-level strength while simultaneously developing a massive aerobic engine.
What we cover:
-The Origins of the Interference Effect: A look back at the 1980 Hixon study and why its "overtraining" protocol skewed our perception of concurrent training [01:02].
-Fatigue vs. Molecular Biology: Why managing your recovery and total training stress is more critical for your gains than worrying about specific cellular pathways [03:07].
-The novice Advantage: Why beginners and intermediates have almost nothing to fear when combining lifting and running [04:38].
-Strategic Timing and Order: Learn why separating sessions by at least three hours can eliminate nearly all negative impacts on strength adaptations [05:40].
-Managing Intensity and Volume: How to avoid "slapping together" two full programs and instead find the high-leverage movements that provide the best return on investment [08:17].
Whether you're a lifter looking to stop feeling "gassed" or a runner wanting to build injury resilience, get the programming that respects your recovery and maximizes your results: citizenathletics.com
