What effects can be expected from daily morning walks with incremental weights, like adding 1kilogram every 5 days?

Starting off with 25kg or like 60 pounds.

  At some point after like 4 months I'll be walking with 49kg on my back or 105 pounds.

Which is around what military people carry.

But then I'll also keep increasing until I run out of weights, or eventually I'll have to walk around with dumbells in my hands and not just a backpack and a weighted vest.
