Nariokotome Boy is sometimes described as having a classic “runner’s” body: long legs, but relatively short forearms, low, wide shoulders, short toes, arched feet, and narrow hips.
These specimens were formerly classed with Homo erectus. Some writers still prefer that classification. The main difference is that ergaster specimens tend to be found in Africa and to be earlier and more gracile, while erectus specimens tend to be Eurasian, later, and more robust.
The famous Nariokotome Boy died as an early adolescent, important because of the completeness of the specimen. He was probably between 8 and 11 years old and 1.6 m tall. He would probably have grown to about 1.8 m in height (roughly 6 feet).
