FUEL Series 30 Min POSTERIOR CHAIN CLUSTERS Workout | Day 28

30 Min Posterior Chain Clusters Workout is Day 28 in Caroline Girvan‘s Fuel Series. Another killer workout! These Fuel workouts are definitely kicking my butt! Caroline works your posterior chain (back, glutes and hamstrings) really well in this workout, but the exercises actually work other muscle groups well, too. Lunges work your entire lower body and those pull overs hit everything. In fact, during the cluster sets of the pull overs my triceps were starting to protest! This is definitely more of a full body workout. I’m considering creating an Iron Fuel rotation that mixes the two programs together (Iron Series + Fuel Series). I think the two programs would compliment each other nicely.

This workout is done interval style but the interval lengths vary. Since there are no set interval lengths (and sometimes no rest/recoveries between exercises), everything is in the breakdown below. There is a timer in the upper right hand side of the screen counting down your intervals and recovery. During the recovery Caroline previews the next exercise. If there is no recovery, a video will appear near the end of an interval previewing the next exercise. There is also a little bar at the bottom of the screen that counts down the entire workout time as a percentage. This workout is done to music with plenty of visual cues as well as “dings” to keep you on track. If an exercise has impact, Caroline shows a low impact alternative.

30 Min Posterior Chain Clusters Workout is 38:42 minutes; 1:43 minute intro, no warm up and 4:20 minute stretch. Equipment: dumbbells, booty band/resistance loop, yoga block, chair or bench, and fitness mat. Caroline is using 15kg/33.1 pound and one 30kg/66.1 pound dumbbells. The weights listed below are what I used.

  1. Hip thrusts for 60 seconds (lean back against your bench or step, band around thighs/above knees, knees bent and open so there is tension on band, feet on floor and one heavy DB on hips, keep legs open so there is constant tension on the band, raise and lower hips/glutes) (one 50# DB)
  2. 20 second rest
  3. Repeat #1 at a faster pace for 20 seconds (one 50# DB)
  4. Repeat #2 & 3 two more times
  5. 20 second rest
  6. Body weight only explosive hip thrusts for 60 seconds (same position as #1 but no DB, thrust hips up fast and lower slowly)

  10. Repeat #8 & 10 two more times
  11. Banded squats for 20 seconds (band is still around thighs above knees)
  12. Banded squat jumps/explosive for 20 seconds (low impact: squat and when you stand, raise onto toes)
  13. 20 second rest
  14. Renegade rows for 60 seconds (alternate arms) (30# DBs)
  15. 20 second rest
  16. Double arm bent over row for 20 seconds (30# DBs)
  17. Repeat #15 & 16 two more times

  20. 20 second rest
  21. Sumo hold (lift at 10 second beep) for 20 seconds (one 60# DB)
  22. Repeat #20 & 21 two more times
  23. 20 second rest
  24. Repeat #11-13
  25. Slow eccentric pullover for 60 seconds (lower DB slowly and raise at normal speed) (one 35# DB)
  26. 20 second rest
  27. Pullovers at a normal pace for 30 seconds (one 35# DB)
  28. 10 second rest
  29. Repeat #27 & 28 two more times
  30. RDL for 60 seconds (Romanian deadlifts) (40# DBs)
  31. 20 second rest
  32. Repeat #30 for 20 seconds
  33. Repeat #31 & 32 two more times
  34. 20 second rest
  35. x1 DB forward leaning lunge for 60 seconds (stationary lunges w/ front foot elevated on a yoga block, hold one DB in same side hand as back leg, torso is hinged forward over front leg) (one 25# DB)

  1. Great idea for a Iron/Fuel rotation! I’ve considered doing one week Iron, one week Fuel, etc. for 12 weeks, but I’d be curious to see what you come up with.

    1. I’m not sure how I will mix it up but alternating weeks is a good idea. I am not doing all Fuel workouts, so I will probably mix them up within each week. I am taking a break from Fuel next week then finishing out the last of the Fuel workouts I plan to do the last week in January. So I’ll probably post it early February.
