Ran with leg weights for 30 seconds, heart rate was 166, rested for 2 mins and it went to 113, is that healthy? it takes ages to go to normal 69bpm

Routine testing: The reduction to 113/minimal might be normal. However, ones doctor can provide routine testing, including a TSH level (thyroid function test) to make sure to exclude hyperthyroidism which could cause a higher heart rate. In general, the more one exercises regularly the lower the heart rate and the more rapid the post-exercise heart rate returns to normal.
