<p>A treadmill with a trampoline-like surface provides an improved peripheral support which tensions the belt in both longitudinal and lateral directions using pairs of angularly oriented springs each pair extending from a roller bracket at an angle of, e.g., forty-five degrees (45 DEG ) to the lateral edge of the mat, connecting thereto at spaced apart positions. The improved spring support tensions the belt with both longitudinal and lateral (or transverse) load components.</p> |
