Do you invest while paying off loans?

I have been listening to Dave Ramsey and although i don’t agree with everything he says, I still find it very useful. One of his teachings is to pay off loans first and invest when debt free. We have a huge amount of student loans and I feel like if we don’t invest (aside from 401k), we’re losing time. We were contributing to a brokerage account but the Ramsey way is to put that towards loans. Loans will be either be paid off or forgiven in 10 years. What’s your take on this?
