Live Your Best Life Ever


Longevity Lab NYC


Longevity Lab presents a formula for living one’s best life ever with a focus on aging with strength and grace. Knowing that no single approach is right for every individual, Longevity Lab emphasizes customized programs and a curriculum of sustainable fitness regimes that can extend your healthy life span and total body-mind health. 


Often times people shy away from working on themselves after a certain age or after life moments - or worse - they jump into a fad that strengthens one muscle group while setting the rest of the body up for potential injury. Longevity Lab looks at those moments as springboards to long-term holistic health and happiness. 


The brainchild of trainer and life coach Aleksandra (Ola) Stacha-Fleming, Longevity Lab has a dedicated client roster of accomplished professionals with an evolving curriculum of self-care that allows her clients to be the strongest versions of themselves inside and out.
