Hypertrophy Advice: What to Trust and What to Question with Dr Gerard McMahon

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

• Periodisation and long-term programming for muscle and strength

• Tendon training, tendon stiffness and high mechanical loading

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.
