If you want an arm workout, choose heavier weights and use them separately from your walking.
Holding light dumbbells at best will have no benefit, at worst cause injury.
If you want to add intensity to your walking, carry extra weight in a backpack, add hills, or walk faster.

Never underestimate the strength of a woman.
Never f@#k with one who runs 26.2 miles for fun.
