Punch with 5 lb dumbbell

[Kung Fu Wang]

When I did my 4 miles walking/training yesterday, I held my 5 lb dumbbell and did 1,480 punches - jab, cross, hook, uppercut, overhand. It was a great feeling afterward.

Have you ever punched with 5 lb dumbbell weight?

It's so funny that when I pay attention on my arms with dumbbell weight, I totally forget about how far that I have walked and how tired my legs can be.

Have you ever had this kind of experience that you concentrate on one part of your body and totally ignore the rest part of your body?
