Crosstraining (XTR) Program Interval (INTV) Program

XTR INTV

This EFX5.21i program consists of alternating forward and backward pedaling movements, in 1-minute segments, to focus on working the thigh and calf muscle groups. Display prompts indicate when you should change pedal direction.

You can set the resistance and ramp incline levels during the forward and backward intervals. The program remembers your settings and repeats them for subsequent forward and backward intervals until you change them.

When you complete the program, the resistance and ramp incline changes are saved and applied the next time you use the Crosstraining program.

The EFX5.21i Interval program is among the best for conditioning your cardiovascular system. The program raises and lowers your level of exertion repeatedly for a specified period of time. You can set the 2-minute rest and work intervals according to your training regimen.

When you begin the program, you are prompted to set the resistance and ramp incline for the first rest and work intervals. Refer to Diagram 9. The settings are repeated throughout the program.
