How do you actually measure muscle growth?
In this episode of Muscle Intelligence, Ben Pakulski sits down with Dr. Eduardo De Souza, one of the top hypertrophy researchers in the world, to break down the real science behind building muscle.
They unpack why most studies don’t use the gold standard (MRI), how ultrasound stacks up, and whether training volume, exercise selection, or rep schemes truly matter. They explore the myths around sarcoplasmic hypertrophy, how aging affects muscle quality, and what actually determines growth after 40.
Whether you’re a coach, athlete, or lifelong lifter, this is essential knowledge for training smarter, not just harder. Get ready for a deep, clear, and evidence-backed conversation on hypertrophy like you’ve never heard before.
Points To Watch Out For
- MRI is still the gold standard for hypertrophy
- Ultrasound can be a valid, cheaper alternative
- Aging muscle shows more fibrous, non-contractile tissue
- High volume ≠ always better gains, individual response matters
- Effective Reps Model lacks peer-reviewed validation
