2. Angry

If you have had a bad period at work or are going through a breakup that is not upsetting you, just angering you, then why not work out all those frustrations in the boxing ring!? Not only does boxing get you super fit, but it also gives you the chance to be super aggressive in a controlled, constructed environment. You might not know how many feelings you needed to get out until you are absolutely pounding a poor defenseless punch bag!
