[solidcore] Unveils 2026 Core Collective, Expanding Member Experience Through Leading Wellness Partnerships

The 2026 Core Collective cohort reflects an evolution in how [solidcore] shows up for its community, supporting not just the workout itself, but the routines that fuel members both inside and outside of the studio. The 2026 expansion builds on growing member demand for deeper integration with the brands they already use to support recovery, nutrition, performance and self care.

Over the coming months, [solidcore] will bring Core Collective to life through a series of high-impact moments designed with each partner and rooted in how its community trains, recovers, and lives. From early access product drops to curated events and brand experiences, these moments will roll out in phases across key markets, giving members an inside track to what's next.

"Being a [solidcore] member has always meant being part of something larger," said Jamey Sunshine, SVP of Brand at [solidcore]. Core Collective deepens that - connecting our members to the brands that fuel their lives, because building strength, physically and mentally, doesn't stop when you walk out the studio door."
