Abstract: A cardiovascular exercise program that includes selectable virtual and real time directed and/or guided exercises particularly adapted for stationary exercise equipment. The program may be performed by individuals in virtual or actual groups. The program allows individual participants to ascertain their ongoing physical conditions such that the participants may customize the exercise program criteria to reflect recognition of such ongoing physical conditions. The program may be performed in a delayed or real-time mode, and includes a particular form of guidance that enables an individual to achieve objectives of self awareness and exercising at appropriate levels through a unique combination of verbal queues, guidance, motivation, entertainment, community, participation, and achievement monitoring. Thus, an individual can increase his or her level of fitness by controlling their perceived level of exertion and the performance of their heart during exercise through guidance and monitoring.

Abstract: A cardiovascular exercise method and system embodying a combination of guidance, motivation, entertainment, community, participation and achievement monitoring. Combined into one integrated system are selectable virtual and real time directed and/or guided exercises particularly adapted for stationary exercise equipment. Such equipment includes spinning bikes, upright bikes, recumbent bikes, elliptical machines, stair stepper/climbers and treadmill/trekers, cross-country simulators and rowing machines. Provision is made for performance by individuals in virtual or actual groups. Also included are audio-visual accompaniment selectable from music, nature sounds and exercise-related sounds for enhancing the exercise experience from the perspective of guidance, motivation, entertainment and achievement monitoring.

Abstract: A fluid-activated, percussive impact tool has a piston therein that reciprocates longitudinally but not rotationally. The piston activates a wrap spring clutch to rotate the drill steel. A removable splined nut in combination with the tool's housing restrains rotation of the piston, while permitting longitudinal reciprocation of the piston.
