Have you thought of carrying small weights while you walk? You could do bicep curls, tricep kickbacks, overhead press, etc while you walk.
I'm the same way. My legs are very strong, but my arms and shoulders are super weak. Start slow with a variety of upper body exercises and add on weight regularly.
When I started working out 8 weeks ago, I could barely do 6 reps of the overhead press with only 10 pounds. Now I'm up to 2 sets of 12 with 40 pounds! I do that, bench press, rows, triceps, biceps, lat pull downs. I also try to hold a plank position for as long as I can several times a week and do some knee pushups.
My goal is to be able to do 10 real pushups...I still can't do one full one all the way to the ground and back up.
I can definitely see some more definition and tone in my arms and keep increasing the weight I'm lifting whenever it starts to get easy to do all 12 reps. Keep it up and you'll start to see results!
