Workout Description
21-15-9
front squats 135 lb
200 meter run
Why This Workout Is Medium
The 21-15-9 rep scheme with 135lb front squats is moderate volume at a manageable load for average athletes. The 200m runs provide built-in recovery between squat sets, breaking up fatigue accumulation. Front squats demand leg strength but aren't a complex skill under fatigue. Total workout time is approximately 12-15 minutes. While not trivial, most CrossFitters can complete as prescribed without significant scaling.

Training Focus
This workout develops the following fitness attributes:
- Stamina (8/10): 45 total front squats demand significant leg muscular endurance. Descending rep scheme (21-15-9) allows some recovery but maintains continuous muscular output throughout.
- Endurance (7/10): The 200-meter runs interspersed throughout create sustained cardiovascular demand. Three runs totaling 600 meters maintain elevated heart rate across the workout duration.
- Strength (6/10): Front squats at 135 lb represent moderate load requiring strength maintenance. Not maximal effort, but sufficient load to demand force production across 45 reps.
- Speed (6/10): For-time format demands quick transitions between squat sets and runs. Minimizing rest between movements and cycling through reps efficiently is critical for performance.
- Flexibility (5/10): Front squats require moderate ankle, hip, and thoracic mobility. Running demands basic lower body range of motion. Standard demands for these movements.
- Power (4/10): Front squats can be performed explosively but descending rep scheme encourages controlled tempo. Runs require some power but are primarily aerobic efforts.
Scaling Options
Reduce load to 95 lb for intermediate athletes or 65-75 lb for newer athletes. If front rack mobility is an issue, substitute goblet squats with a kettlebell (35-53 lb) or back squats at a reduced load. For athletes with significant squat limitations, box squats or dumbbell front squats are solid alternatives. Volume can be reduced to 15-12-9 or 9-6-3 for athletes still building capacity. The 200m run can be substituted with a 250m row or 12-15 calorie bike if running is not an option.
Scaling Explanation
Scale the weight if you cannot perform at least 10 unbroken front squats at the prescribed load with solid mechanics — elbows up, chest tall, knees tracking over toes. If your front rack position causes wrist or shoulder pain, substitute immediately rather than grinding through poor movement. The goal is to finish in 6-12 minutes at high intensity. If you're looking at a 15+ minute grind, reduce the load or reps. Intensity and movement quality are both priorities here — never sacrifice a safe squat pattern for the sake of Rx weight.
Intended Stimulus
Fast to moderate sprint effort lasting 6-12 minutes. This is a high-intensity chipper that demands both leg strength and cardiovascular output. The front squat load combined with short runs creates a brutal cycle of muscular fatigue and aerobic demand. Expect your legs to be on fire and your lungs working hard — this is a hard sustained effort with sprint intentions.
Coach Insight
The front squats are the limiting factor here — respect them early or pay for it in the round of 15. In the round of 21, consider breaking into 12-9 or 11-10 rather than going unbroken and blowing up. The 200m run is your active recovery — use it to shake out your legs and control your breathing before the next set of squats. Keep your elbows high on the front rack to protect your wrists and maintain an upright torso. The most common mistake is letting the elbows drop under fatigue, which dumps the bar forward and destroys your midline. Don't rush the turnaround on the run — a controlled pace on the 200m will pay dividends when you pick the bar back up. In the round of 9, go for broke on both movements.
Benchmark Notes
Front squat cycling at 135 lb is the primary limiter — athletes must manage quad fatigue across 45 total reps broken by short runs. L5 (~7:30) breaks squats into sets of 12-9, 8-7, 5-4 and runs at moderate pace. Elite athletes cycle squats in large unbroken sets and run fast.
Modality Profile
Front Squat is a Weightlifting movement (barbell with external load). Run is a Monostructural movement (cyclical cardio). Two movements, one from each modality = 50/50 split.
