Which collaborations has Randy Aikens engaged in to enhance his fitness content?

The available content does not clearly list any formal collaborations (like brand deals, co-programs, or named creator collabs). The clips in view focus on solo training, motivation, and bodyweight/fitness work such as the “3 movements, three rounds, 30 seconds each” style workouts and #TheWork / #BuiltNotPosted content.

There may be collaborations elsewhere, but they are not visible in what is pulled here.

Are you asking about brand partnerships, co-coaching with other trainers, or guest appearances (podcasts, radio, events)?
