Abstract: A vest assembly includes a bodice having at least one front pocket and at least one back pocket. A neck collar attaches to the bodice. Preferably, the neck collar includes compressive material to provide cushion and resistance. A collar adjustment, typically an elasticized material, providing adjustable resistance to the neck collar. A plurality of compressive inserts can be selectively inserted in the front pocket and/or the back pocket of the vest assembly. Each compressive insert is a compressive material to provide resistance to a frontal area of a chest of a user. The plurality of compressive inserts are interchangeable and come in varying weights and compressive and/or tensile strengths.
