The story

A full-body transformation in her mid-50s — and what it taught her.

How Seana-Marie rebuilt the way she trains, eats, and recovers — and the road map that followed.

Strength, movement, and what's possible after 40

Seana-Marie Sesma is a dynamic fitness coach, competitive bodybuilder with NPC and OCB, and entrepreneur dedicated to empowering others to thrive — physically, personally, and professionally.

After decades of ups and downs with weight and wellness, she committed to a full-body transformation in her mid-50s. Now, in the best shape of her life at 60+, she inspires others to evolve with strength, joy, and self-belief.

As a rhythm cycle instructor, certified Les Mills BODYBALANCE™ coach, and practitioner of other body and strength modalities, Seana-Marie brings movement, music, and mindfulness together to create an inclusive space for people to build strength and flexibility at every life stage.

Her wellness practice also includes the use of MAKE Wellness peptides, which she champions for supporting recovery, metabolism, and hormone balance in midlife and beyond.

At her core, Seana-Marie believes in evolving boldly and helping others do the same. Whether she's leading a fitness class, building brand magic, or mentoring entrepreneurs, she shows up with integrity, energy, and a passion for transformation.
