Pietro Rimondini is a former D1 tennis player at Cornell University who turned post-grad gym-less training into a full fitness brand. Born in Italy, raised in the US, he now runs Genno Fit and Built From Home — helping men build muscle anywhere, no gym required, through structured, progressive bodyweight programs. Pietro Rimondini was a nationally ranked junior tennis player in the US, reaching as high as #17 in the country in 2014–2015. He earned main draw wildcards in USA Futures events before committing to Cornell University as a five-star Tennis Recruiting Network prospect — one of the most competitive D1 programs in the Ivy League. At Cornell, he competed for years under the discipline of elite athletic training while earning a degree in Hotel Management. After graduating, without regular gym access, he began filming home workouts in his living room, posting them online, and building an audience organically. That eventually became Genno Fit and the Built From Home app — a full fitness coaching platform now followed by hundreds of thousands across Instagram, TikTok, and YouTube.
