Question about heart rate?

Question

I am a 28 year old male, been lifting weights regularly for the past year. i have just recently started cardio exercise. My resting heart rate is 54. when i get my heart up to 120 very quickly like with 2 minutes of jumping jacks, it goes back to 65 Bpm within 1 minute. Immediately after stopping jumping jacks my heart rate is 120. 1 minute later it is 70 then 1 minute after that it is at 65. what i'm saying is that it goes back down very fast. is this a bad thing?

Answer 1

Obviously you are super fit.  If you weren't then it would take much longer for you to recover and get back to your normal bpm at rest.
