I had a few weird heart rhythms...sort of like a series of missed beats...would happen at random, I STOPPED taking flax seed oil capsules and it went away. I read somewhere about flax seed oil causing that in some people. At that time my only physical activity as such was work, which IS over 6,000 steps and 20 or more flights of stairs :-). But the arrhythmia or whatever it was would happen when I was sitting sedentary.
