Muscles need strong tendons and cartilage to grow bigger, or they'll break.
Scientific Claim
Muscle growth requires a supportive infrastructure of tendons, fascia, and cartilage to withstand mechanical loading.
Original Statement
“Your body doesn't just need muscle fibers to grow. It needs the entire infrastructure around them. Tendons, fascia, cartilage. It needs them to be strong enough to handle more loading. Growth doesn't happen if the scaffolding cannot sustain the work.”

Triphasic 3D In Vitro Model of Bone-Tendon-Muscle Interfaces to Study Their Regeneration
Researchers created a special 3D model to study how bone, tendon, and muscle connect and heal, which is important for understanding how muscles grow and work properly.
This study looks at how muscle and tendon work together when we exercise, and how different cells help them adapt to the stress of physical activity.
Technical explanation
This paper directly studies the adaptation of the muscle-tendon unit to mechanical loading, showing that spatially distinct ECM-producing fibroblasts and myonuclei orchestrate early adaptation.

Stimulation of type II collagen biosynthesis and secretion in bovine chondrocytes cultured with degraded collagen
This study only shows that broken-down collagen can make cartilage cells produce more cartilage collagen — it doesn’t say anything about muscles, tendons, or how they work together during exercise.
