Can i begin a fitness career having sinus bradycardia?

Probably: That recommendation should come from your doctor. However, a lot of athletes - especially aerobic athletes - have sinus bradycardia. Their hearts are able to deliver enough blood flow and maintain a reasonable blood pressure even at a slow pace . Your doctor will be in the best position to advise you.

Probably: The reasons for your bradycardia should be known to you. If you're taking a prescribed rx that reduces your resting heart rate it may be difficult for you to increase your hr in response to exercise. This could limit your ability to pump oxygen more quickly and efficiently thereby limiting your ability to "push yourself." no matter...See an md to sort out the "why, " first!
