Accessing JSON objects nested inside array

I've been trying to access the JSON from this API. However, when I run a request to retrieve the JSON I'm met with the following list when I run this code.

const request = require('request');

var url = 'https://api.collegefootballdata.com/rankings?year=2019&week=10&seasonType=regular'
request(url,(err, res, body) => {
    if(!err && res.statusCode == 200) {
        var obj = JSON.parse(body);
        console.log(obj);
    }
});

My output:

[
  {
    season: 2019,
    seasonType: 'regular',
    week: 10,
    polls: [ [Object], [Object], [Object] ]
  }
]

My problem here lies in the fact that I want the information from each POLL (5 polls listed as objects in the JSON by following the link, however I cannot figure out how to WORK with this.) For example, I would want to call polls[0].rank to populate a list of the top 25 teams from the poll.

Accessing the arrays of objects inside nested JSON has obviously been a problem for me in Node, and would love to get started on the right foot when working with this project.
