FitByNature

FitByNature Boxing offers outdoor fitness boxing in Hamburg’s Stadtpark, welcoming participants of every fitness level. Led by trainer Christoph Kieselbach, its sessions use high-intensity interval boxing workouts (HIIBT) and take place in small groups, combining guided exercise with a supportive team atmosphere. The training is designed for people who want to improve their fitness, lose weight, or work toward a new personal goal. Alongside an athletic workout, participants can practise skills intended to support self-defence and build confidence, energy, and physical strength.

FitByNature presents its training as a way to become part of a local community while focusing on fitness and wellbeing. Sessions are scheduled on Mondays and Thursdays from 6:30 to 7:30 p.m. in the Stadtpark; participants are directed to meet at the Pinguinbrunnen. The website invites newcomers to register for a free trial session and provides a contact form for questions. FitByNature is a neighbourhood-based option for people seeking structured, professionally guided boxing-inspired exercise outdoors rather than in a conventional gym.
