I’m Isma A. Colarusso, a certified personal trainer, functional fitness coach, nutrition specialist, and mobility practitioner in Stuyvesant, NY. I help clients in Hudson, Valatie, Kinderhook, Chatham, and surrounding Columbia County build strength, improve endurance, and reach their fitness goals. My programs include one-on-one personal training, hybrid coaching with CrossFit- & Hyrox-inspired workouts, mobility training, nutrition guidance, and small group sessions. All training is at my private studio or online — I do not travel to clients. Programs are designed for clients who want motivation, accountability, and lasting results.
