A chest exerciser includes an elongated plunger housing and a pair of plungers that move in sealed sliding contact with the plunger housing on opposite sides of a common air volume within said plunger housing. An adjustable vent, centrally located between the plungers, communicates with the common air volume. Each plunger is attached to a hand grip. The handles slide on and are coaxial with the plunger housing. In the fully retracted position the grip distance between the proximal end of said first plunger hand grip member and the proximal end of said second plunger hand grip member is between 0 and 10 inches. The exerciser is used in combination with a breast enhancement nutrient, such as pueraria mirifica, which may be applied to the breast as a cream or tonic or ingested as an herb or pill.
