Interval 1-1 and Interval 1-2
Interval workouts help exercisers improve strength,
endurance, aerobic and anaerobic fitness. They
alternate short bursts of high intensity activity with
recovery periods.
These workouts are designed to raise and lower your
heart rate in a repeating fashion for a user-defined
period of time by alternating rest and work intervals of
two minutes each (for the Interval 1-1 workout) and
two minutes of rest followed by four minutes of work
(for the Interval 1-2 workout).
Training tip:
You can further tailor your rest and work
period intensity by adjusting the resistance,
CrossRamp setting, or both at any time. The
equipment remembers these preferences for each
upcoming interval.
