Unproductive
: Your training load is at a good level, but your
fitness is decreasing. Your body may be struggling to
recover, so you should pay attention to your overall health
including stress, nutrition, and rest.
Detraining
: Detraining occurs when you are training much less
than usual for a week or more, and it is affecting your fitness
level. You can try increasing your training load to see
improvement.
Overreaching
: Your training load is very high and
counterproductive. Your body needs a rest. You should give
yourself time to recover by adding lighter training to your
schedule.
No Status
: The device needs one or two weeks of training
history, including activities with VO2 max. results from
running or cycling, to determine your training status.
Tips for Getting Your Training Status
The training status feature depends on updated assessments of
your fitness level, including at least two VO2 max.
measurements per week. Your VO2 max. estimate is updated
after outdoor runs or rides during which your heart rate reached
at least 70% of your maximum heart rate for several minutes.
The trail run and indoor run activities do not generate a VO2
max. estimate in order to preserve the accuracy of your fitness
level trend.
To get the most out of the training status feature, you can try
these tips.
• At least two times per week, run or ride outdoors with a
power meter, and reach a heart rate higher than 70% of your
maximum heart rate for at least 10 minutes.
After using the device for one week, your training status
should be available.
• Record all of your fitness activities on this device, or enable
the Physio TrueUp
™
feature, allowing your device to learn
about your performance (
Syncing Activities and Performance
).
About VO2 Max. Estimates
VO2 max. is the maximum volume of oxygen (in milliliters) you
can consume per minute per kilogram of body weight at your
maximum performance. In simple terms, VO2 max. is an
indication of athletic performance and should increase as your
level of fitness improves. The D2 Charlie device requires wrist-
based heart rate or a compatible chest heart rate monitor to
display your VO2 max. estimate. The device has separate VO2
max. estimates for running and cycling. You must run either
outside with GPS or ride with a compatible power meter at a
moderate level of intensity for several minutes to get an
accurate VO2 max. estimate.
On the device, your VO2 max. estimate appears as a number,
description, and position on the color gauge. On your Garmin
Connect account, you can view additional details about your
VO2 max. estimate, including your fitness age. Your fitness age
gives you an idea of how your fitness compares with a person of
the same gender and different age. As you exercise, your fitness
age can decrease over time.
