Approach: the human outcome. Palette: bold color field, mustard yellow.

A tight, low-angle side view of an older man's muscular calf and thigh mid-leg-press or seated leg extension, shot from knee level. His weathered, sinewy skin shows fine hair and visible tendon definition, and his hands rest on the knee. He wears a plain charcoal athletic short and a worn white sneaker. The backdrop is a seamless saturated mustard-yellow wall, with a matte black gym machine frame cutting diagonally through the frame. Soft, directional studio light from camera left creates gentle highlights on the quadriceps and a warm shadow. A small electric green resistance band is looped around his ankle as the only green accent. The face stays out of frame. The mood is determined, strong and quietly hopeful, with a shallow depth of field and a crisp editorial feel.

Catatannya, plasebonya adalah silika, bukan protein, sehingga tambahan protein saja mungkin menjelaskan sebagian efeknya. Berikut temuan studi, mengapa kolagen mungkin membantu, dan siapa yang bisa mendapat manfaat.
