Fast & Dirty Circuit Workout | Alex Silver-Fagan
Six moves, four rounds, and almost no rest — that’s the whole plan.
Alex Silver-Fagan built her “Fast & Dirty Circuit Workout” for exactly the kind of session its name promises: short, punishing, and over before you have time to complain about it. The Cellucor and Bodybuilding.com athlete, who trains clients as a personal trainer and group fitness instructor at CityRow in New York City, put together a six-exercise, total-body circuit meant to spike heart rate and torch calories without a single wasted movement. It works as a standalone fat-burning workout or as the metabolic-conditioning finisher tacked onto a heavy lifting day.
- The circuit is built from six exercises, each performed for 8 reps (or 8 reps per side), completed for 3 to 4 rounds with as little rest as possible between movements.
- Silver-Fagan designed it to double as either a standalone fat-burning workout or the cardio/metabolic-conditioning finisher on a heavy lifting day.
- She blends powerlifting, bodybuilding, CrossFit, and circuit training into the programming, competing in the past herself before shifting toward what she calls “living a fit lifestyle” that mixes bodybuilding, CrossFit, yoga, running, powerlifting, and circuit work.
The Six-Move Circuit
The workout runs through burpees with a side-to-side shuffle, split squats with a shoulder press, decline push-ups with a cross climber, dumbbell front squats into a rotational press, renegade rows, and an overhead reach paired with a toe-tap leg extension. Each move gets 8 reps — or 8 reps per arm/leg on the unilateral exercises — before moving straight into the next. Silver-Fagan’s instruction is blunt about pacing: minimal rest between exercises is the point, since the whole design leans on keeping heart rate elevated rather than resetting it between sets.
That structure is what separates this from a standard strength circuit. Instead of isolating muscle groups one at a time, movements like the front squat-to-rotational press and the overhead reach with toe-tap force the hips, shoulders, and core to fire together, which is why Silver-Fagan frames the session as multi-planar rather than just full-body.
My fast-and-dirty circuit is how I think circuits should be: quick and effective.
Built for Multiple Planes of Motion
Every exercise in the circuit was chosen to move the body through more than one plane — forward, lateral, and rotational — rather than the straight sagittal-plane grind of a typical gym session. The side-to-side shuffle off the burpee, the rotational press off the front squat, and the cross climber off the decline push-up all add a twisting or lateral component on top of the base movement. Silver-Fagan describes the goal as raising the metabolic demand of the workout without dropping load or intensity, which is also why she pairs strength-based moves (renegade rows, front squats) with cardio-heavy ones (burpees, shuffles) in the same six-move sequence.
For readers stacking this into a broader training week, it slots in the same category as other short, high-output finishers — the kind of session covered in 10 HIIT Exercises to Lose Belly Fat FASTER, where the emphasis is on density of work rather than total time on the clock.
From Competition Stage to CityRow Instructor
Silver-Fagan is upfront that she’s competed before but doesn’t treat competition prep as the only valid marker of fitness. “I think it’s a good goal, but by no means does it equal living a fit lifestyle,” she says of her own competitive background, pointing instead to a training week that rotates through bodybuilding, CrossFit, yoga, running, powerlifting, and circuit training. That range shows up directly in this circuit’s exercise selection — split squats and front squats borrowed from powerlifting, burpees and renegade rows from CrossFit-style conditioning, all stitched into one continuous set.
Readers looking to pair this kind of circuit with a leaner eating approach can find complementary programming in pieces like 3 Science-Based Tips to Lose Belly Fat, which covers the nutrition side of the same fat-loss goal this circuit targets on the training side.
Run it as written — 3 to 4 rounds of all six moves, minimal rest between exercises — and the whole thing is done in well under 20 minutes, which is exactly the “fast and dirty” pitch Silver-Fagan built it around.
