I found this awhile ago, and to me, these reasons ‘feel’ better than all the physical benefits lists (bone density, strength, flexibility, heart health and so on). I like the idea of changing focus for each month, too. It doesn’t have to be “to run” either. It could be any physical activity you enjoy!
January – New Beginnings
February – Efficiency & Strength
March – Health & Vitality
April – Achievements & Satisfaction
May – Feel Good Factor & Adrenaline Rush
June – Variety & Stimulation
July – Fun & Participation
August – Adaptability & Versatility
September – Sociability
October – Appreciation of Nature
November – Simplicity & Independence
December – Weight Loss & Maintenance
What ‘feel good’ reasons do you have to exercise?
