Coach Maya

KlynShape · Weight loss

28 days Bodyweight All levels

A physical-transformation specialist, Maya has guided dozens of people toward real, lasting weight loss — no gym, no equipment, just bodyweight and a method that progresses every week.

Her approach combines rigor, movement intelligence and recovery: every session is designed to be sustainable over time, not just intense one day and dropped the next.

« Discipline · Aesthetics · Energy · Spirit. »

28 days Dumbbells & bands Progressive

A passionate fitness coach, Lena has spent several years guiding women and men toward their fitness and weight-loss goals, with light dumbbells and resistance bands.

Coach Onyx

KlynMilitary · Calisthenics

28 days Calisthenics Advanced

A strength-and-conditioning specialist and performance coach, Onyx draws on 8 years of intensive calisthenics training to build a demanding program: discipline, explosiveness, iron mindset.

KlynMilitary isn't designed to be easy — it's designed to transform. Every week ramps up the intensity, all the way to advanced calisthenics moves you never thought you could do.

« Excellence is not a talent. It's a habit. »

Coach Atlas

KlynBuild · Strength training

28 days Gym Start & Strong

A strength-training and hypertrophy coach, Atlas builds his programs around a 4-phase periodized method: activation, accumulation, intensification, realization — the same logic as professional strength coaches.

Whether you're starting out at the gym or want to structure a stalling routine: Build Start to lay the foundations, Build Strong to go after volume.

« Confidence · Energy · Progress. »

Coach Kaia

KlynMind · Yoga & Meditation

28 days Yoga & meditation All levels

A certified yoga teacher and mindfulness specialist, Kaia built KLYN Mind as a 28-day space to reconnect the body, the breath and inner balance.

Breathing, guided meditation, accessible postures: her approach assumes the mind supports the body as much as the reverse. KLYN Mind is included in every program, like a daily ritual.

« Calm is the foundation of all power. »

From −18 kg to founding
KLYN

My name is Virginie. For years, I searched for a program that truly fit me — not a generic plan, not an empty promise. I wanted real, lasting results, without sacrificing my life.

In 3 months, with the method I built from scratch, I lost 18 kg. No extreme diet. No daily gym. Just a structured, progressive approach, tailored to my body and my pace.

KLYN is that method — made accessible to everyone. Because if it worked for me, it can work for you.
