How would you fit yoga into this exercise routine?

I lift weights 6 days a week,alternating upper and lower body on opposite days.I do some form of aerobic exercise 7 days a week from 30 minutes to an hour or more.I want to start yoga again (about an hour routine) but am not sure where to fit it in.Should I combine the weights to one day?Should I split up the yoga or do it daily??Where would I get the most benefit…—without dropping dead of exhaustion?
