Mid-40s man. Is heart rate hitting low 180s during cardio safe, or should this be concerning? (lemmy.world)

I'm in my mid-40s and I do cardio 3x weekly, and during my sessions, it's basically HIIT training. I try to keep my HR above 150 during my sessions, but it peaks in the low 180s intermittently.

Is this okay? My doctor noted potential concerns with getting my HR up that high, but it could be fine, she wasn't sure. I don't get any dizziness or anything (generally that happens if I sustain a heart rate above 185 for a bit). I'm not staying at 180 bpm, that's just the peak, I'm targeting an average HR of around 150-155 for my workouts.

In a 60 minute workout, I'll probably spend 10-15 minutes with my HR between 166 and 182 range.

Not sure if I should scale it down a bit or take it easier, or if this is fine.

Could be it's the watch, it's a Garmin Vivoactive 6.

I've ignored one-off high readings that only last for like a second spike, I'm going by specific heart rates that I peak at and sustain that I can monitor for a few seconds even if I stop moving.

The typical formula is 220-age, but I’ve found that it can definitely miss the mark

Same, and by that metric I'd be dead. 😂 I've hit 190 bpm, and regularly get into the 180s, but standard metric would have my absolute max in the 170s. I can sustain 170 bpm for several minutes without even feeling too stressed.

Finally, it helps to know if there are any underlying cardio respiratory issues that would impact the strength of your heart.

No issues there, good heart health. Occasionally high triglyceride profile (depends heavily on what I eat the day before a lipid panel) and frequent slightly lower than optimal "good" cholesterol on my lipids, but that's about it. Overall cholesterol is low, and my doc gave me a clean bill of health with my heart (literally saw the doctor this morning for my annual checkup, awaiting my blood work later this week).
