Depends: Normal heart rate is 60-100 bpm. Having said that, in healthy, fit and conditioned individuals a resting heart rate as low as 30-40 BPM can be seen because their heart is conditioned and at rest is not needing a lot of oxygen, so does not beat fast. When that person exercises, and o2 and blood demands go up to their skeletal muscle etc, heart rate will increase. Hope that makes sense.

Not necessarily : You may be athletic and your resting heart rate could be lower -- so how are you feeling when the heart rate is lower ?
