Multi-purpose functional ruck weight

A weight comprising:

• a body bounded by a top surface and a bottom surface, each having a major dimension and a minor dimension, and separated by a thickness of opposing side edge surfaces and proximal and distal end edge surfaces to define a spatial envelope of the body configured such that, in a packing mode, the body is carryable flat against a body of a user, wherein the thickness is less than the minor dimension and the body is reflectively mirrored about a bisecting longitudinal axis relative to the minor dimension of the top surface;
• a first swing handle defined by the proximal end edge surface, the opposing side edge surfaces, and a first aperture extending through the body from the top surface to the bottom surface at a proximal end of the body, the first aperture having a major axis aligned with the minor axis of the top surface, the first aperture configured such that, in a two-handed swinging mode, a first hand and a second hand of the user are spatially distributed and oriented along intersecting axes;
• and,
• a grip handle distal to the swing handle, the grip handle defined by a second aperture and a third aperture each extending through the top surface and the bottom surface, the grip handle configured such that, in a dumbbell mode, the first hand of the user is inserted through the second aperture and the third aperture to grip the grip handle at a center gravity of the body, wherein a total width across the second aperture and the third aperture in the minor dimension of the top surface is less than a width of the first aperture in the minor dimension of the top surface;
• wherein the top surface includes a recess parallel to the axis orthogonal to the longitudinal axis of the body, configured such that the recess is located near the proximal end of the body distal to the first aperture.
