Thanks, really surprised garmin doesn't say what the test entails in the manual.

Cheers for this buddy. Have a fenix 6 pro turning up any day now.

Well...A heart rate strap will be on the list for fathers day...Love your vids. I was recently diagnosed with Diabete's type II and exercise is keeping my sugar low and my energy level high. I want to learn everything I can about my Fenix 5x sapphire.

[sebastianwegel]

Really well done and explained. Thank you!

Thanks for the video. Great instruction 🙏

Thanks for these videos, really useful. Your videos allow me to use my Fenix 5x as I want to but didn’t know how to. “You’ll need a current VO2 max reading-already tested.” How do I go about that?

[richarddownes]

Can you measure your lactate threshold by outdoor cycling instead of running? I cycle, rather than run. If so, can you get a vo2 max. by cycling also rather than running?

[DavidBigandt]

I tried it today and could not sustain the pace it wanted me to

[christophbeckmann]

Good Video...is it necessary to own a garmin cheststrap or do others Work too???

[mountainlife]

Do you need the chest strap? Dont really want to buy one just to set this up?

[gutodocolas]

Hi, can I use a HR cheststrap from another brand?

[randalljohnson]

Can this be used on a spin bike instead of running?

Sorry but which button do I have to press to start the test? The Light one?
