Questions & Answers about В спортзал я обычно хожу в толстовке, а не в пиджаке.

Why is the verb хожу used here, not иду?

Because ходить is the multi-directional / habitual verb of motion. In this sentence, обычно shows a repeated habit: I usually go.

• я хожу в спортзал = I go to the gym / I usually go to the gym
• я иду в спортзал = I am going to the gym right now, in one specific direction

So обычно хожу is the natural choice for a routine.

Why is в used twice, and why does it seem to mean different things?

The preposition в is doing two different jobs here:

1. в спортзал = to the gym
   Here it expresses motion toward a place.

2. в толстовке, в пиджаке = in a sweatshirt, in a jacket/blazer
   Here it expresses what someone is wearing.

Russian often uses в + Prepositional for clothing after verbs like ходить, быть, сидеть, etc.:

• ходить в пальто = to go around wearing a coat
• быть в шляпе = to be wearing a hat

So even though English uses different wording, Russian naturally uses в in both parts.
