They used a steadycam for those shots, which allows the camera to be carried while still giving a smooth shot. The one they used in that film was a larger backpack style, to help support the weight of the camera and equipment, but there are smaller versions for DSLRs and smaller cinema cameras such as the GlideCam. There are also electronic gimbals in use now that can give an even smoother shot when used correctly. Both steadycams and gimbals have advantages/disadvantages, but the end result is similar; a smooth tracking shot that isn't limited to a tripod or jib.
