Fantastic post!As someone who has battled weight, depression, respiratory illness, allergies, anxiety, etc etc, and is now in the best shape of my life, I can strongly vouch for the wide reaching effectiveness of exercise.
There are almost no parts of my existence that have not been enhanced by improved fitness, including profession, cognition, and relationships.As people increase their level of fitness they most commonly improve their nutrition, which has a multiplying effect on the deep impacts of fitness.Lian hit the nail on the head, work out for life, make it fun and find something that works for your life, but do not forget to push your comfort level a bit.
