De Krachtbox is an outdoor fitness gym in Amsterdam offering three training formats: Kracht Workout (combining weightlifting, athletics, and gymnastics with functional movements), Box Workout (explosive bag training), and Bootcamp (group-based conditioning and strength). Classes use functional equipment including barbells, kettlebells, medicine balls, ropes, and TRX, with training conducted on grass fields. The gym suits those seeking high-intensity, varied workouts focused on functional strength and power development without traditional gym amenities.
For race-specific work, the gym has a sled track — the kit that matters most for practising sled push and pull efforts at competition standard. Members rate it 5.0 out of 5 across 26 Google reviews.
