You'll need the Rogue Landmine Handle (the angled one), but it's absolutely worth the purchase if you're trying to smash the yoke.
This exercise is sort of a pairing of mini-rows and shrugs. They really smash the middle and upper traps while also bringing in the rhomboids. Shrug and row together, lifting the shoulders up and then pulling the elbows back as well. Hold the top of each rep for at least 3 seconds before lowering.
Do 4 sets of 10-12 reps and your traps and upper back will be smoked.
The last time it happened I was getting changed in the locker room at my gym. Two pudgy-bellied gym members (PBGMs) were discussing the relative virtues and drawbacks of doing cardio as part of their training program.
