If you train for hypertrophy, you are probably not short on advice.
The harder part is knowing which advice is worth trusting.
In this episode of Stronger With Time, Tony speaks with Dr Gerard McMahon, a muscle physiology and biomechanics researcher and applied practitioner who has worked with elite athletes across Olympic, Para Games and Commonwealth Games environments.
Gerard brings together research and applied practice: what drives muscle growth, and what that means when you are programming for real people over months and years.
Together, Tony and Gerard work through some of the most common claims in hypertrophy training, from mechanical tension and effective reps to volume, activation drills, lengthened partials, periodisation and tendon training.
In this episode, they discuss:
Why research and real-world coaching both matter
What actually triggers muscle hypertrophy
Mechanical tension, muscle damage and metabolic stress
Why “effective reps” and “stimulating reps” are often misunderstood
How training volume should change with training status
Why more sets in one session are not always better
What muscle activation drills can and cannot do
Lengthened partials, lengthened range and where they may be useful
Why lengthened training does not apply equally to every muscle
Social media echo chambers in hypertrophy advice
Drop sets, supersets and high-fatigue methods
Periodisation and long-term programming for muscle and strength
This conversation is for coaches, personal trainers and experienced lifters who want to think more clearly about hypertrophy training and build programs from principles rather than trends.
