What’s Trending

Arnold Schwarzenegger has officially partnered with Momentous, deepening a long-running relationship into a multi-year collaboration built around science, discipline, and long-term performance.

Why It Matters

This isn’t a celebrity endorsement chasing trends. It’s an alignment around what has worked for more than 60 years.

Schwarzenegger has seen every fitness cycle come and go—from bodybuilding’s golden era to modern biohacking—and his philosophy hasn’t changed: master the basics, execute consistently, and avoid shortcuts. Momentous operates from the same playbook, with every product NSF Certified for Sport® and built on clinical research rather than hype.

In a market flooded with “longevity hacks,” this partnership signals a return to durable performance fundamentals.

Inside The Arnold Stack

The stack focuses on proven essentials that support performance, recovery, and longevity:

• Protein – to support muscle, metabolism, and daily recovery
• Creatine – for strength, power, and cognitive support
• Vitamin D3 – for bone health, immunity, and overall resilience

Together, they represent a dual seal of credibility: decades of Schwarzenegger’s lived experience paired with Momentous’ uncompromising quality standards.

Bigger Picture

Momentous continues to expand its footprint across elite sport, the U.S. military, and high-performance communities—now reinforced by one of the most trusted voices in fitness history. The partnership will activate through content, product launches, and major events, including the Arnold Sports Festival in 2026.

The Playbook Take

Health trends rotate. Fundamentals compound.
Arnold choosing Momentous reinforces a growing signal in performance and longevity: the future isn’t about more supplements—it’s about better standards, fewer products, and long-term consistency.
