I've noticed a few random bruises on my body lately! i do exercise 4-5x/wk and am in otherwise good health! any explanations? should i be concerned?

Usually normal: A few bruises can occur from exercise or accidentally bumping your arms or legs. If you take aspirin, advil or other nsaids, they can make you bruise more easily. In addition, vitamin e, fish oil, garlic, ginseng, ginkgo biloba, and alcohol such as in red wine can make you more prone to bruising. If bruises are presistent, you should see your doctor to check blood work including CBC and pt/ptt/inr.
