Workout Description

Why This Workout Is Medium

This workout combines moderate volume (132 total reps + 84 calories) with light loads but creates significant fatigue through a 36-minute time domain. The ascending-then-descending ladder structure forces athletes to manage pacing carefully—early rounds feel easy but accumulate fatigue, while the peak (round 6: 12 box jumps + 12 thrusters + 14 calories) hits when already fatigued. The 3-minute windows provide minimal rest, and box jumps demand fresh legs. Most average CrossFitters will complete it, but the combination of sustained effort, leg fatigue from repeated jumping, and the mental challenge of a long workout makes this Hard rather than Medium.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): High total rep volume across 12 rounds (156 box jumps, 156 DB thrusters, 84 ski calories) tests muscular endurance. The ascending-descending ladder format prolongs fatigue accumulation and recovery demands.
• Endurance (7/10): The 36-minute EMOM structure with ski erg calories (4-14 cal per round) demands sustained cardiovascular output. Continuous work with minimal rest between rounds creates moderate-to-high aerobic demand throughout.
• Power (6/10): Box jumps are inherently explosive movements, and DB thrusters require power generation. However, fatigue accumulation reduces explosive capacity as rounds progress, limiting pure power expression.
• Speed (5/10): The EMOM format with fixed 3-minute windows creates pacing pressure. Athletes must cycle movements efficiently to complete work and earn rest. Transitions between movements matter but aren't sprint-paced.
• Strength (4/10): Light dumbbell loads (10kg) and bodyweight box jumps don't challenge maximal strength. The final farmers walk adds some strength demand, but overall stimulus is muscular endurance over pure strength.
• Flexibility (3/10): Box jumps and DB thrusters require moderate hip and ankle mobility. Ski erg demands basic shoulder mobility. No extreme range of motion requirements; standard CrossFit movement positions suffice.

Movements

• Farmer Carry
• Dumbbell Thruster
• Ski Erg
• Box Jump

Scaling Options

Weight: Reduce DB Thrusters to 2x6kg or 2x8kg for newer athletes or those with shoulder mobility limitations. Farmers Walk KBs can drop to 2x12kg or 2x8kg. Movement substitutions: Replace Box Jumps with Box Step-Ups (same height, lower impact) or reduce box height from standard 24/20 inches to 20/16 inches. Sub the Ski Erg for 1.5x the calories on a rower or 2x the calories on an Assault Bike if no Ski Erg is available. Volume modifications: For beginners, run the workout as an 8-round version (rounds 1-4 ascending, rounds 5-8 descending) with the Farmers Walk still in the final round. Alternatively, cap the peak round at 8 reps per movement (reduce Round 6 from 12/12/14 to 8/8/10) to keep rest intervals meaningful throughout.

Scaling Explanation

Scale if you cannot complete the peak round (Round 6: 12 Box Jumps, 12 Thrusters, 14 cal Ski Erg) in under 2 minutes when fresh — if that feels impossible, the rest intervals in the middle rounds will evaporate and the workout becomes a suffer-fest rather than a stimulus. Prioritise technique over load on the Thrusters: if your lower back rounds or your elbows drop during the squat at Rx weight, reduce the load immediately. The Farmers Walk in Round 12 should feel heavy and challenging but controllable — if 2x16kg KBs cause you to hinge and lean excessively, drop to a load that lets you walk tall. The intended goal is to finish every round feeling like you had 30-45 seconds to spare in Rounds 1-4, and 15-30 seconds in Rounds 5-11, with Round 12 being a near-max effort on the walk. Intensity is the priority here, but only intensity that can be sustained with safe movement patterns across all 36 minutes.

Intended Stimulus

This is a moderate time-domain interval workout designed to build aerobic capacity and muscular endurance through a pyramid structure. Each 3-minute window targets a hard-but-sustainable effort — think 80-85% output — with built-in rest rewarding efficiency and smart pacing. The ascending ladder builds cumulative fatigue while the descending ladder tests your ability to maintain quality when your legs and lungs are already taxed. The primary challenge is metabolic conditioning paired with mental discipline: resisting the urge to blow out early rounds and having enough left in the tank to push the final Farmers Walk in Round 12. Energy demand is a sustained aerobic engine with repeated short power bursts — not a sprint, not a grind, but controlled intensity across 36 minutes.

Coach Insight

The biggest mistake athletes make in ladder workouts like this is treating Round 1 like a sprint. Those early rounds should feel almost too easy — they are your warm-up within the workout. Aim to finish Rounds 1-3 in under 60-70 seconds, giving yourself 2+ minutes of rest. As reps climb in Rounds 4-6, target completion within 90-105 seconds. On the Ski Erg, maintain a smooth pull rather than hammering — this is your transition to rest, not a sprint finish. For DB Thrusters, keep elbows high in the rack and drive through the heels; at 2x10kg the load is light, so the risk is rushing and losing midline stability. Box Jumps should be controlled — step down rather than jumping down on higher-rep rounds to protect your legs and Achilles over 12 rounds. The descending rounds (7-11) will feel deceptively harder than the ascending because cumulative fatigue has set in — respect that. In Round 12, blast through the single rep and immediately grab the 2x16kg KBs for your Farmers Walk. Stand tall, brace your core, take short controlled steps, and switch grips only if needed. Your score is total reps plus calories, so maximise distance in that final window — it's where bonus points live.

Benchmark Notes

The primary limiters are the ski erg calorie pace in rounds 5–6 (12–14 cals under fatigue) and thruster cycling with 2x10kg after accumulated box jumps. L5 targets exactly completing all 12 rounds' fixed work (242 total reps + cals) with minimal farmers walk bonus, meaning they're managing each 3-minute window close to the wire by rounds 5–6. Higher levels separate on farmers walk volume in round 12 and faster transitions buying more rest.

Modality Profile

Box Jump is Gymnastics (bodyweight), Ski Erg is Monostructural (cyclical cardio), Dumbbell Thruster is Weightlifting (external load), and Farmers Hold is Weightlifting (external load). 1 G + 1 M + 2 W = 25% G, 25% M, 50% W
