About

Cezary Sadowski is a Personal Trainer at Longevity Sport Lab with nearly two decades of coaching experience. His athletic background spans two very different demands: he was a junior bodybuilding champion of Poland and national-team competitor, then moved into endurance sports, obstacle racing, cycling, and mountain ultramarathons, including a completed 100 km race. At LSL, that range matters because he can build plans for people chasing strength, general fitness, or long-distance goals without treating those goals as separate worlds.

What to Know

Signature approach

Cezary coaches through individualization and long-term cooperation. The starting point is the client's current capacity, then training is built toward strength, endurance, or event preparation without losing the habit-building layer that keeps people consistent. LSL's tools, including VO2 max, HRV, and body-composition testing, give him a measured baseline instead of relying only on perceived effort.

What sets them apart

  • Strength plus endurance. Junior bodybuilding national title on one side, mountain-ultra experience on the other. That combination is unusual in a personal trainer and useful for clients balancing muscle, conditioning, and durability.
  • Long coaching tenure. Nearly 20 years supporting clients, with the company-submitted bio emphasizing trust, individualized plans, and long-term cooperation.
  • Current practitioner mindset. His goals include longer mountain running and Ironman 70.3, so he is still training through the stress-and-recovery questions he asks clients to manage.

Before You Book

  • Training emphasis. He is a strong choice for strength, endurance, general fitness, and long-distance preparation. For regulated physiotherapy or post-injury rehab, use Jakub Grzyb.
  • Visit format. Training is in-person at Myśliwiecka 4a and works best when paired with LSL's testing and recovery cadence.
  • Goal setting. Bring a concrete training goal or performance constraint; his approach is built around individual programming rather than generic sessions.
