Kettleboxing-official

Kettleboxing is a fitness brand based in Amersfoort, Netherlands, offering a dynamic workout that combines kettlebell training with boxing. Designed as a full-body session for different fitness levels, its approach brings strength and cardio together in one 45-minute workout. Participants use kettlebells and punch bags to develop conditioning, strength, coordination, speed and reflexes, while engaging the core and grip. The brand also highlights practical benefits such as efficient training, functional power and a focused outlet for stress.

Kettleboxing works with sports clubs and gyms that want to add the workout to their programmes. It offers an instructor training pathway for fitness professionals, covering kettlebell and boxing-bag techniques, safety, technique and teaching skills. Participants complete an examination and, if successful, receive certification as Kettleboxing instructors. The training is personally guided by Joop Kasteel, whose experience spans strength and combat sports. Based at Palladiostraat 82 in Amersfoort, Kettleboxing invites individuals and sports organisations to contact the team about participation, club offerings and instructor education. The website also includes a shop.
