Just start small. Almost runners take too big of strides which is bad for the whole body. U want about 180 strides per minute (short and quick)Im a newbie for archery, but for rifle I still try to get to 5'10'' 180 need to bulk up a little tho. Do any of you run? I am wanting to get into it now that my gym is shut down, but man Ill tell ya what I hate running! But I really need to start, its just that 1st week i dread.
Sounds like you may have more muscular legs/glutes than the average guy. At 6'2" it would be easy to carry extra muscle/weight in your legs compared to the average guy who's shorter with thin legs. Think running back vs cornerback.
