Abstract
A treadmill with a trampoline-like surface provides a 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.degree.) to the lateral edge of the mat, connecting thereto at spaced apart positions. The spring support tensions the belt with both longitudinal and lateral (or transverse) load components.
