Precor 5.19 ユーザーズマニュアル

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.
