Workout Description

5 rounds for time: 7 muscle-ups 1 sandbag over 3 logs (Rounds 1-4 = (100/150 lb), Round 5 = (125/200 lb)

Why This Workout Is Hard

For the average CrossFit athlete, Muscle-up Logs is Hard because Sandbag Over Log at up to 200 lb and Muscle-Up meet a roughly 5:48 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.

  • Beginner: >9:26

Training Focus

This workout develops the following fitness attributes:

  • Speed (7/10): The 5:48 scoring window and 2 movements score 0.7 for speed; success rewards repeatable cycling, decisive transitions, and appropriately aggressive pacing.
  • Strength (5/10): External loading and force demands score 0.5 for strength. The prescription reaches about 200 lb before sex-specific scaling. Force production must remain technically sound as the workout's other demands accumulate.
  • Stamina (3/10): The repeated work around Sandbag Over Log at up to 200 lb and Muscle-Up scores 0.3 for stamina; athletes must preserve local muscular output as sets, rounds, and transitions accumulate fatigue.
  • Power (3/10): Sandbag Over Log at up to 200 lb and Muscle-Up drive a 0.3 power score through controlled force rather than maximal explosiveness.
  • Endurance (2/10): Muscle-up Logs scores 0.2 for endurance because its 5:48 domain creates cardiovascular demand through sustained output. Breathing supports repeatable work, but pure aerobic capacity is not the only limiter.
  • Flexibility (1/10): The prescribed positions create a 0.1 flexibility demand: efficient range of motion matters, but mobility is supportive rather than the sole test.

Movements

  • Muscle-Up
  • Sandbag Over Log

Scaling Options

Reduce Sandbag Over Log to a load that permits crisp small sets without failed reps. Replace Muscle-Up with pull-ups plus dips.

Scaling Explanation

Choose options that keep the athlete working in the short, high-output domain without prolonged failure. Preserve the primary challenge of Sandbag Over Log at up to 200 lb and Muscle-Up, not the exact Rx load or skill at the expense of intensity.

Intended Stimulus

Muscle-up Logs is intended as a short, high-output test centered on Sandbag Over Log at up to 200 lb and Muscle-Up. 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 Sandbag Over Log at up to 200 lb and Muscle-Up 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 5:48 for an average Rx athlete, allowing realistic set breaks and transitions around Sandbag Over Log at up to 200 lb and Muscle-Up. L10 targets 2:47 with deliberate pacing, near-unbroken skill work, and minimal transition loss.

Modality Profile

Counting each unique movement once, G includes Muscle-Up; W includes Sandbag Over Log. That produces G 50%, M 0%, and W 50%.
