The strap device comprises an elongated and resilient strap with movable contour shoulder pads of a shock absorbing material with the overall length of strap being adjustable. The hand holds located at each end of the length of strap are also adjustable. The strap device is uniquely placed on the upper body to employ a rhythmic movement of exertion upon inhaling and relaxation when exhaling. This uniform motion of exertion and relaxation of the uniquely placed strap device on the upper body opens up the air passages and improves breathing, allowing a greater amount of air to be inhaled and exhaled.
