Esta página está disponible en español

We are back with episode 9 of the podcast Between Thresholds... and again a week late. We hope it won't happen again!

In today's episode we are loaded with technology. So much so that I almost didn't let Jose talk. The truth is that news have been accumulating in the last two weeks, so there was a lot of material to talk about...

Starting with the new watches from Garmin solar-charged vehicles that have been introduced this week. The Garmin Fenix 6 Solar, Garmin Fenix 6S Solar and Garmin Instinct Solar I told you about on Wednesday. In addition to reviewing the launch we also talked a little bit about interesting facts about the charging system and what may be the future of the technology within the Garmin range.

On the part of Polar we have the new Polar Unitethe new fitness watch from the Finnish company. I'll tell you what are the fundamental differences with respect to the Polar IgniteThe new GPS system is a little more than just the absence of GPS.

Y Suunto was also present, with a couple of new developments for its application and for the Suunto 7.

Of course, pod could not leave out what will probably be the most important news of this year in the segment: the purchase of Firstbeat by Garmin. We explain the operation and the consequences it may bring to the sector.

And of course we answer your questions! As every week, we clear up any doubts you have left us. through the web form. So if you want us to answer something in particular, click on that link and send us your question.

As for episode notes, a clarification must be made regarding Garmin models that support specific functions.

Answering Rodrigo's question, these are the models that support the Body Battery feature.


  • Approach S62
  • fenix 6 series
  • Forerunner 245/245 Music
  • Forerunner 45/45S
  • Forerunner 945
  • Garmin Swim 2
  • Legacy Hero Series
  • Legacy Saga Series
  • MARQ Series
  • tactix Delta
  • vivosmart 4
  • vivomove 3/3S
  • vivomove Style
  • vivomove Luxe
  • vivoactive 4/4S
  • Venu

To put it in a nutshell, these are the models that incorporate the latest optical pulse sensor with the blood oxygen estimation sensor. If yours doesn't have that sensor, you don't have the Body Battery option. And in the case of Rodrigo and his Fenix 5 and Forerunner 645... you can't find that option because they don't have it.

It is a similar answer that we give to Miguel, who asks us about the lactate threshold test that some Garmin have. In his case he has a Forerunner 245, and asks us where it is for poder to do it.

Indeed, you cannot find it because it is not available on the FR245. These are the models that do offer it:

  • D2 Bravo
  • D2 Charlie
  • D2 Delta series
  • Descent MK1
  • fenix 3
  • fenix 3 HR
  • fenix 5 series
  • fenix 5 plus series
  • fenix 6 series
  • fenix Chronos
  • Forerunner 630
  • Forerunner 645/645 Music
  • Forerunner 735XT
  • Forerunner 935
  • Foreunner 945
  • MARQ series
  • quatix 3
  • quatix 5
  • tactix Bravo
  • tactix Charlie

For models that do allow this test, here is what you will need:

  • Chest pulse sensor (not suitable for optical pulse sensor).
  • A more or less updated VO2Max value (that establishes heart rate zones to work in). Therefore, do not do it with the newly purchased or reset watch.
  • Test outdoors with GPS.

It is started from the watch menu, under training -> Lactate threshold test.

From there the watch takes us through different intervals, starting very smoothly. It indicates a target pace to be met along with heart rate data. You simply have to complete the different steps until the watch indicates that you have finished. It is not an excessively hard test so you have nothing to fear.

The watch will also detect threshold changes without the need for the test, throughout the workouts. But for this we have to train with a pulse sensor on the chest in the same way as for the test.

  1. Hello gentlemen. I am Rodrigo, again from Colombia. Thank you very much for answering my questions. I swear by my mother (God save her) that both the FR645 and the Fenix 5 show me the faces at the end of the workout (I clarify that it is after the guided workouts, which are programmed from the Connect app with the trainers that Garmin has and directly on the watch). Today I was going to send you a picture when I got the faces, but I did not know how to attach it here, so if you tell me where I can send it, in the next training I take a picture or a short video for you to see it. Thanks and great job.

    1. Ok, so it is a specific function of the Garmin training programs. I was totally unaware of it (both Jose and I program we do the workouts through Training Peaks).

      Thank you so much for the clarification, you've taught me something new!!! 🙂
