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.
If you're a bodybuilder and you've spent your weightlifting life doing sets of 8,10, 12, etc., doing singles will absolutely blow you up. A terrific idea and a terrific program that'll raise you head and shoulders above the competition.
