Biography
Petar Krastev
Petar Krastev, known professionally as Coach PK, is an award-winning executive fitness coach helping busy leaders rebuild their health in under 3 hours a week.
His full name is Petar Stefanov Krastev, written Петър Стефанов Кръстев in Bulgarian. He is the founder of Coach PK and the creator of the Peak Performance Protocol, the coaching system he built for business owners and senior professionals who have the discipline to succeed at work but no realistic way to fit training into the week.
Background
Krastev was born on 24 August 1991 in Varna, Bulgaria. He left the country in 2014 with ten euros and a suitcase, landing at Luton airport with almost no English. He spent his first eighteen months in the United Kingdom living in a garage without electricity or running water. He has been open that the gym was what held him together through those years, not as a goal but as the one thing that gave him direction.
In 2018 he committed to sport and coaching full time. In the years since he has built a coaching practice serving business leaders internationally, and founded Limitless Body And Mind, a community for health and fitness professionals that grew past 2,000 members. During its run he spent more than a thousand hours in conversation with specialists in nutrition, strength and conditioning, athletic performance and sports science, work that shaped the evidence-led approach he coaches from today.
He is based in Ho Chi Minh City, Vietnam, and coaches clients internationally. The business itself, Calisthenics UK Limited, is registered in England and Wales.
Coaching
Krastev coaches one to one, personally, rather than delegating clients to junior coaches. The Peak Performance Protocol combines efficient training, portion-based nutrition, sleep and recovery, mindset and direct accountability. Its stated promise is deliberately conservative: 20 to 50 lbs of fat lost on under three hours of training a week, without the client stepping back from their business or their family.
Underneath it sit three named frameworks he developed and tested on his own life and on his clients: PACE (Precision Aligned Conditioning Exercise) for training, SPC (Smart Portion Control) for nutrition without calorie counting, and GAIN (Growth Accountability Inspiration Network) for the support model.
