An exercise apparatus includes a frame, an arm supporting member, and a
leg supporting member. A sensor is connected to at least one of the arm
supporting member and the leg supporting member, and/or a resilient
member is interconnected between the arm supporting member and either the
leg supporting member or the frame. The sensor communicates with a user
display and/or a resistance device to indicate the amounts of work
performed by the arm supporting member and the leg supporting member,
and/or to adjust resistance to movement of the leg supporting member as a
function of user force applied against the arm supporting member. The
resilient member encourages synchronization of the arm supporting member
and the leg supporting member, while allowing some relative movement
therebetween. A user interface displays data associated with exercise
activity, including relative amounts of work performed by a user's arms
and legs and/or performed during different phases of exercise, including
discrete aerobic and anaerobic phases. The interface display and the
level of resistance are preferably changed as part of the transition
between phases.
