I agree with that 100% I walk as many days possible, 2 miles in the afternoon. It is getting to be the tough time of the year as yesterday it was 96 degrees while walking. I, also, have a Total Gym and use that to strengthen my arms, back and legs several times a week.
If I don't walk and use resistance training I, literally, have trouble getting out of bed and doing household chores and lawn work.
I listen to music.
Great contribution.
