Workout Description

For Time 172 foot Sled Push 18/15 Bar Muscle-Ups 172 foot Sled Push Time Cap: 6 minutes

Why This Workout Is Very Hard

Short time cap, high-skill gymnastics, and a heavy odd-object push make this a very hard sprint. Athletes must combine powerful sled accelerations with 18/15 bar muscle-ups under fatigue. The skill ceiling and pacing demands are high, and small mistakes (missed reps, failed turnovers, sled stalls) are heavily penalized in such a tight window.

  • Intermediate: 3:40-4:00
  • Beginner: >6:00

Training Focus

This workout develops the following fitness attributes:

  • Speed (9/10): This is a true sprint. Quick transitions, minimal chalk, and decisive breaks matter. Fast bar cycling and continuous sled steps without stalls reward velocity and composure more than conservative pacing strategies.
  • Power (7/10): Explosive hip drive to get over the bar and forceful sled starts are decisive. Athletes who can produce high force quickly will cycle reps faster, accelerate the sled cleanly, and minimize time lost in transitions.
  • Stamina (6/10): Upper-body pulling and dip stamina on the bar plus continuous leg drive on the sled matter. Holding large sets on muscle-ups and steady sled steps without pauses tests repeatability under accumulating fatigue.
  • Strength (5/10): The sled demands meaningful lower-body and trunk strength to keep momentum, especially through turns. Bar muscle-ups require strong pulling and pressing, though loads aren’t maximal—submaximal strength expressed repeatedly under fatigue.
  • Endurance (3/10): A short, high-intensity effort that limits pure aerobic pacing. You’ll breathe hard, but the cap makes this more anaerobic. A solid engine helps, yet conditioning isn’t the primary limiter compared to skill and power output.
  • Flexibility (2/10): You need adequate shoulder and thoracic mobility for stable arch-hollow shapes and a strong support position over the bar. Hip extension for a powerful kip helps. No extreme ranges beyond standard gymnastics positions.

Scaling Options

Scale to: Lighter sled + 12/9 Bar Muscle-Ups • Moderate sled + 18/15 Chest-to-Bar Pull-Ups • Light sled + 24/18 Pull-Ups or Jumping Bar Muscle-Ups

Scaling Explanation

These options preserve the sprint stimulus by matching upper-body skill to capacity and adjusting sled load so athletes can keep moving fast without repeated failures or long rests.

Intended Stimulus

Fast, aggressive sprint with no wasted motion. Push the sled with constant steps, then hit one or two big sets of muscle-ups before a quick final push. Heart rate spikes, forearms and triceps burn, and legs stay under tension. Finish fast without redlining so hard you fail reps or stall the sled.

Coach Insight

Open with a steady but assertive sled—no pauses. Aim for 1-2 planned MU sets with tiny breaks. Sprint the final sled. The one tip: Commit to your first MU set. Big, efficient reps save the most time. Avoid over-chalking, sloppy turns with the sled, and going to failure on the bar. Missed reps are costly.

Benchmark Notes

Times represent finish times from beginner to elite. If you’re near the cap (6:00), you likely broke the bar a lot or stalled the sled. Mid-tier athletes should aim around 4:00. Elite performances will keep sleds moving and muscle-ups in big sets, finishing near 3:00.

Modality Profile

Two movements: an external-load sled push and high-skill bar muscle-ups. The sled likely consumes more time and energy, so weightlifting dominates. No monostructural element. Gymnastics remains substantial because 18/15 advanced reps in a short time domain significantly shape the workout’s demand and pacing.
