YouTube: Visual Journaling and Daily Routines
YouTube is Marvin’s visual journal, focusing on short-form content through YouTube Shorts. With 382K subscribers, he primarily repurposes popular clips from Instagram and TikTok to maintain consistency. While he isn’t highly active, his most viral Shorts reach tens of millions of views. This channel supports brand presence through search visibility and long-term content value.
Despite the low posting frequency—only 2.2 videos a month—his best videos perform exceptionally well. Clips like his morning routines or coaching sessions have hit 30M+ views, demonstrating that quality beats quantity. However, with an engagement rate of just 0.34%, this platform is more passive in his strategy. It acts more as a viewer funnel than an interaction hub.
Marvin’s YouTube approach emphasizes storytelling through visually compelling, concise edits. His tone remains consistent with other platforms: motivational, clean, and goal-oriented. The Shorts format fits well with his coaching style, allowing viewers to absorb information quickly. These videos also serve as teasers for his full coaching programs and lifestyle.
Although growth has plateaued, the platform still plays a crucial role in his brand ecosystem. His content is evergreen and benefits from YouTube’s powerful recommendation algorithm. With improved frequency or longer content formats, Marvin could easily scale on this platform. Right now, YouTube remains a strong secondary pillar for visibility and SEO.

X (formerly Twitter): A Glimpse Into His Personal Life
On X, Marvin shares the raw, unfiltered parts of his journey, adding a more personal layer to his brand. With 42.2K followers, he tweets daily, using the platform like a journal. His posts often include reflections on his relationship, life changes, and moments of gratitude. This side of Marvin reveals his vulnerability and emotional depth.
He tweets an average of 6.8 times per week, often sharing behind-the-scenes moments that don’t appear on other platforms. X allows him to engage in real-time conversations and stay connected with fans on a more casual level. While his engagement rate is only 0.17%, the intimacy of the platform compensates for the low numbers. It’s not about volume here—it’s about connection.
Most tweets revolve around personal updates, motivational snippets, and big announcements. For example, his move to Poland and relationship milestones are shared openly. This gives his followers a “friend-like” experience, increasing loyalty and trust. X also gives Marvin a space to show his humor, opinions, and real-world reflections.
Although X isn’t a high-growth platform for him, it serves as a valuable support channel. Posting daily at 4 AM ensures visibility during a consistent window. For Marvin, Twitter is less about strategy and more about presence. It rounds out his persona, adding depth beyond the fitness and video content.
