Fortunately we have common tools to measure stress and recovery rate (HRV in garmin or polar watches). And the latest ones don't even need a chest heart rate strap. Go hard and fast when you train, make sure you get at least 2 days of rest per week and most importantly get good sleep and rest. In case of doubt , check HRV indicators

I've been shopping for one of those devices and the latest reviews report that wrist heart rate sensors aren't very accurate under hard exertion. And there's no scientific evidence that HRV as measured by those devices is correlated with the risk of a cardiac event.

  I've been pretty happy with my Garmin Vivoactive HR for cycling -- I too was worried that it would be wildly inaccurate, so I did a few rides with both the Garmin (using its wrist sensor) and my old Polar watch with a chest strap to compare them. They were very close to each other -- both on the bike looking at live readings and later looking at the charts at home. However, it could see it having less accuracy with an activity with more arm motion, like running. And I have no evidence that my Polar sensor was very accurate itself.

    Yes, the primary concern with optical wrist sensors is "cadence lock", which is when they start measuring the wiggle of the arm rather than the beating of the heart.

  I have the Garmin Forerunner 620, and I will buy a cheaper model next time. I have found the recovery indication useless (see comment above).

I have found the recovery indication in the Garmin Forerunner 620 useless. I'm not sure it even really looks at HRV. As far as I can tell, it only looks at the intensity of the previous workouts. Case in point: if you do a workout without heart rate sensor, it won't tell you how 'recovered' you are at the beginning of your next workout.

  My more recent Garmin will use HR data during the exercise to determine recovery HR by simply comparing activity HR to the HR two minutes after you've paused the activity. But even if you're not using a HR monitoring device during your workout, being vigilant on your resting HR provides a good clue. Too high and you need to rest, whether from overtraining or illness.
