Seb Prentice was 24 when his mom passed away. She was in London, he was in Cape Town. Three weeks from hospitalization to gone.
At the time, he was earning R70-110K a month in tech sales, living rent-free in Sea Point. He quit, took his savings and his mom's life policy, and opened a gym. He moved out of his flat and into the gym itself to keep costs down. He started every single month in the red.
Three years later, Horizen Gym is arguably the most talked-about fitness space in Cape Town. He has 15 employees, a second location in the works, and a vision to become the world's number one lifestyle strength brand by 2040. The gym still ran an accounting loss this year.
In this episode, Seb gets real about everything why opening a gym is a financially terrible idea (and why he did it anyway), what it actually costs to run a brick-and-mortar fitness business, the ego death that comes with learning to manage people, and the radical accountability lesson from his mom that became Horizen's foundational value. Her words "cry me a river" and "don't be a victim" still run through everything he builds.
We also talk about running a sub-3 marathon and a 100-miler while building a business, why the fitness industry is over-optimized and under-trained, and what it means to do for strength training what run clubs did for running.
This one hit different for us. Hope it does for you too.
