This one works best when using a cable column that has both a high and low setup. Place an EZ-bar attachment on the low cable and attach rope handles to the high cable.
A1 Rope Face Pull
A2 Rope Triceps Pressdown
A3 EZ-Bar Biceps Curl
Do 2-4 sets, 8-16 reps per exercise, resting 1-2 minutes before repeating the sequence.
Instead of doing EZ-bar curls, you can attach a single handle to the low cable and perform either face-away biceps curls or single-arm cable curls.
With mechanical drop sets, instead of reducing the load, you switch to a new but similar exercise by changing the grip, angle, etc. The result is a whole lot of burning and a whole lot of growth.
