A few things I think

A few things I think landed well in this edit:

Storytelling structure Instead of opening straight on the expert, the trailer opens on a hook, then cuts into a fast historical montage cave drawings, primal hunters, gladiators before landing back on Felipe. That sequence does the positioning work for you: it frames strength training as something ancient and instinctive, not just another gym routine, right before the brand drops the line "La ciencia detrás del cuerpo que quieres." By the time his name card and title ("Especialista en Entrenamiento") hit, the authority is already earned instead of just stated.

Color grading One consistent grade carries the whole piece deep blacks, red practical lighting bleeding through the interview and every B-roll insert. It's a moodier, more cinematic look than typical fitness-creator content, closer to a documentary trailer, and it keeps the historical footage and the modern interview feeling like the same world instead of two mismatched sources cut together.

Sound design & music The mix builds in swells that peak right on the cuts that matter the title card reveal, the name card, and a final hit synced to the FitClass logo at the very end. That's what makes the cuts feel intentional rather than just "music playing under talking head" the score is doing edit work, not just filling silence.

Pacing Interview cuts get just enough room to breathe so Felipe's lines land, while the B-roll/historical montage moves faster to keep tension up the contrast in rhythm is part of what sells the "then vs. now" idea before the reveal.
