hi i am 23 is it normal to have heart rate at 55 while doing biking exercise in gym? it was my 1st time. my trainer really scared me today when she started to take my test while biking. for the 1st 3 minutes i my heart rate was around 95 and i had an target of 120 which i did achieve but soon i was getting tired and my heart rate gradually dropped to 55. my trainer said that it is not normal and that she has never seen anything like that. . does that mean i might have heart problems soon. . i am always very healthy just haven't been doing any exercise for 5 years. please could you help me.
