Workout Description
For time:
30-calorie Echo bike
15 muscle-ups
72-foot dumbbell walking lunge
Time cap: 6 minutes
♀ Two 70-lb dumbbells
♂ Two 100-lb dumbbells
Why This Workout Is Hard
For the average CrossFit athlete, Semifinals 24.6 is Hard because Muscle-Up and Dumbbell Walking Lunge at up to 100 lb meet a roughly 6:00 work domain. The movements interfere through repeated grip, trunk, leg, or overhead fatigue, and there is little built-in recovery, so local fatigue compounds across movements. Many average athletes will need to scale at least one limiter.

Training Focus
This workout develops the following fitness attributes:
- Speed (8/10): The 6:00 scoring window and 3 movements score 0.8 for speed; success rewards repeatable cycling, decisive transitions, and appropriately aggressive pacing.
- Endurance (3/10): Semifinals 24.6 scores 0.3 for endurance because its 6:00 domain creates cardiovascular demand through sustained output. Breathing supports repeatable work, but pure aerobic capacity is not the only limiter.
- Stamina (3/10): The repeated work around Muscle-Up and Dumbbell Walking Lunge at up to 100 lb scores 0.3 for stamina; athletes must preserve local muscular output as sets, rounds, and transitions accumulate fatigue.
- Strength (3/10): External loading and force demands score 0.3 for strength. The prescription reaches about 100 lb before sex-specific scaling. Force production must remain technically sound as the workout's other demands accumulate.
- Flexibility (3/10): Dumbbell Walking Lunge create a 0.3 flexibility demand: efficient range of motion matters, but mobility is supportive rather than the sole test.
- Power (2/10): Muscle-Up and Dumbbell Walking Lunge at up to 100 lb drive a 0.2 power score through controlled force rather than maximal explosiveness.

Scaling Options
Reduce Dumbbell Walking Lunge to a load that permits crisp small sets without failed reps. Replace Muscle-Up with pull-ups plus dips. Reduce monostructural distance or calories to roughly 70-80%.
Scaling Explanation
Choose options that keep the athlete working in the short, high-output domain and capable of meaningful progress inside the 6:00 cap. Preserve the primary challenge of Muscle-Up and Dumbbell Walking Lunge at up to 100 lb, not the exact Rx load or skill at the expense of intensity.
Intended Stimulus
Semifinals 24.6 is intended as a short, high-output test centered on Muscle-Up and Dumbbell Walking Lunge at up to 100 lb. Athletes should sustain the fastest repeatable output that preserves the prescribed standards, letting breathing and local fatigue build without turning early aggression into failed reps or long stops.
Coach Insight
Start at a pace you can repeat through the middle of the workout, and break Muscle-Up and Dumbbell Walking Lunge at up to 100 lb before technique or cadence collapses. Keep transitions deliberate and short; save the final acceleration for the last round or station.
Benchmark Notes
L5 is anchored near 3:07 for an average Rx athlete, allowing realistic set breaks and transitions around Muscle-Up and Dumbbell Walking Lunge at up to 100 lb. L10 targets 1:30 with deliberate pacing, near-unbroken skill work, and minimal transition loss.
Modality Profile
Counting each unique movement once, G includes Muscle-Up; M includes Air Bike; W includes Dumbbell Walking Lunge. That produces G 40%, M 30%, and W 30%.
