通い
"通い" means "commuting" or "regularly going to and from a place."
Here, '通います' (kayoimasu) is derived from '通い' (kayo-i), which signifies regular or habitual travel or attendance to a specific place. It emphasizes a routine action.
私は毎朝学校に通います。
I go to school every morning.
'通っています' (kayotteimasu) indicates the ongoing action of regularly attending or visiting a particular location such as a gym.
彼はジムに毎週通っています。
He goes to the gym every week.
In this context, '通っています' (kayotteimasu) highlights the physical passage or flow through a location, diverging from the habitual attendance usage, showing geographical passage.
