"いつもどこへ行くにも車で移動するので、あまり歩きません"
いつも = always
どこへ行くにも = no matter where I go; everywhere
車で = with a car; by car; drive
移動するので = since I get around
あまり歩きません = don't walk (very) much
Since I always drive myself everywhere, I don't walk very much.
もっと短く
Since I always drive, I don't walk much. <- simple, わかりやすい
他に
I don't walk because I always drive.
いつも車で移動しているから、あまり歩かない。
