Patent ID: 8578517

Claim:
An atmospherically open tight fitting weight lifter's shirt comprising; a torso section sized and adapted to fit snugly about the torso of a weight lifter when worn and a pair of sleeves sized and adapted to fit snugly about the arms of a weight lifter when worn projecting from the torso section and defining shoulders and armpits, the sleeves and a front of the torso section between the armpits being made wholly of a non-elastic fabric which cannot stretch substantially, each sleeve having only one layer of material having a proximal edge, a distal edge and a pair of juxtaposed edges, said juxtaposed edges sewn together with inelastic thread defining a seam thereby forming said sleeve into a tubular formation with said seam extending from said proximal edge to said distal edge, said juxtaposed edges having a curvature such that the seam bends around the sleeve for at least about 90°, said torso section in its relaxed flattened state defining a front section, all of which faces in a first direction, and a back section, all of which faces in a second direction opposite to the first direction, said front section defining arm holes, said proximal edges of said sleeves being attached solely to said front section about said arm holes with at least a proximal section of said sleeves projecting away from said front section, whereby when said shirt is worn by a weight lifter lying in a supine position and said weight lifter flexes said sleeves such as by lowering a set of weights from a position above the torso to a position adjacent the torso causing said sleeves to twist, energy is stored in the shirt upon twisting of the fabric of the sleeves, wherein such energy aids the weight lifter to raise the set of weights back to the position above the torso.
