Narrative:

Out of FL210 during our descent into ZZZ with the autopilot on; I noticed a stab out of trim light. Broke out the QRH and ran the checklist. This is when we discovered we had no electric trim available on either side. This took us to the electric stabilizer trim inoperative checklist. Followed the checklist; [advised ATC] and had to manually trim the nose using trim wheel. First officer continued to fly the airplane while I ran the checklist and talked to ATC. I controlled the trim wheel as the first officer instructed me on nose up or down trim; and the first officer concentrated on the stick and throttles. We were already set up for a straight in for runway xx and used flaps 15 landing (according to the checklist) and maximum brakes. First officer did a fantastic landing and then we proceeded to the gate where we were met by our maintenance team. Debriefed maintenance in ZZZ; went up to the pilot lounge and filled out a [report].
