I think I used to be. I would run to the gym, work out and then run back, and i'd feel guilty if I had a day off. I also started to get very addicted to running and to chasing PBs (personal bests).
Now, I just make sure I walk my 10,000 steps per day, and I do either a run, dance or gym 3 times a week, 4 in summer/if i'm not working.
I have a friend who exercises 7 days a week and does 3 exercises classes in a row, one after the other. Another who will do a 5k run then straight to the gym for a 2-hour workout.
I no longer have a 6 pack but I think I have a healthy and balanced approach to exercise. I think doing several workouts in a day is extreme, but that's just my opinion.
Has anyone else ever considered themselves addicted ?
