Workout Boosters
The xR6 Series elliptical cross trainers offer three unique workout enhancers that provide challenge and variety 
to help you stay motivated and committed to your exercise program. You can add Muscle Endurance, Leg Press, 
or Chest Press to any program at the touch of a button, kicking your workout up to a whole new level!
Muscle Endurance
Muscle Endurance
is a great way to take advantage of the variety your seated elliptical cross trainer offers, and 
is a great motivational tool that keeps your workout fresh and exciting. This booster works in any program; every 
other minute it kicks in, increasing your current resistance level by 4 and prompting you to perform combinations 
of eight different challenges: Push-Legs, Pull-Arms, Push-Arms, Reverse, Fast, Resistance
+
, Narrow Grip, and 
Wide Grip.
Push-Legs  Focus on pushing with your legs to work your quadraceps and glutes.
Pull-Arms  Focus on pulling with your arms to work your biceps and lats at 10 levels higher than your 
current resistance.
Push-Arms  Focus on pushing with your arms to work your chest and triceps at 10 levels higher than your 
current resistance.
Reverse  Pedal backwards to change the muscle focus in your legs.
Fast  Pick up the pace—we recommend 60+ rpm, but you should find your own comfort level.
Resistance
+
  Sweat it out as your work your entire body with a quick burst at 3 additional levels of 
resistance—a total of 7 levels higher than your program resistance level!
Narrow Grip  Grasp the multigrips on the low inside edge to give your triceps and chest muscles a workout.
Wide Grip   Grasp the multigrips high on the outside and feel it in your shoulders, chest, and back.
When Muscle Endurance is active, one to four Muscle Endurance LED combinations will light up instructing you 
what to do. The light sequence is randomly generated so you never know what is coming next.
To activate Muscle Endurance, simply push the Muscle Endurance button while in any program. To turn Muscle 
Endurance off, push the button again. In its original (out-of-the-box) configuration, each Muscle Endurance 
session lasts for one minute. On the xR6e and xR6ce, the countdown timer displays how much time until your next 
Muscle Endurance interval or how much time is left in your current Muscle Endurance interval. Once you complete 
the instruction, you have a one-minute interval in your normal elliptical routine (according to the program you are 
using). After this one-minute period, you will automatically get your next Muscle Endurance routine. Good luck!
Tip: Want to change the length or intensity of your Muscle Endurance intervals on your xR6e or xR6ce? Just press 
and hold the Muscle Endurance button for three seconds, or until you hear a beep. You can then set the time 
for each Muscle Endurance interval and the time between intervals. See page 24 for additional details!
