Workout Description

Why This Workout Is Very Hard

The weight vest transforms an otherwise Hard workout into Very Hard. The 1-mile run buy-in with a vest pre-fatigues the legs and lungs before the AMRAP begins. The vest then compounds every subsequent movement — push-ups become significantly harder, wall balls require more power output, and even sit-ups are affected. Continuous 15-minute AMRAP with no rest built in, combined with 50 total reps per round, creates brutal cumulative fatigue similar to Murph's vest mechanic.

Training Focus

This workout develops the following fitness attributes:

• Stamina (9/10): High-rep movements — 12 push-ups, 10 wall balls, 28 sit-ups — repeated across multiple rounds in 15 minutes under a weight vest accumulate massive muscular endurance demands on the chest, core, and legs.
• Endurance (8/10): The 1-mile run buy-in combined with a 15-minute AMRAP wearing a weight vest creates sustained cardiovascular demand throughout. Continuous movement with added load significantly elevates heart rate and aerobic output.
• Speed (6/10): AMRAP format incentivizes efficient transitions and consistent cycling pace. Athletes must balance moving quickly through each movement with managing fatigue from the vest and prior run to maximize total reps.
• Flexibility (3/10): Wall ball shots require hip mobility and overhead positioning; sit-ups demand spinal flexion range. The weight vest slightly restricts movement. Overall mobility demands are moderate but not extreme.
• Power (3/10): Wall ball shots involve a hip-drive explosive component, but the high rep count and fatigue shift the stimulus away from true power expression toward sustained muscular output over time.
• Strength (3/10): Movements are bodyweight or light load. The weight vest adds modest resistance to push-ups and sit-ups, but this is primarily a muscular endurance workout rather than a maximal strength test.

Movements

• Wall Ball
• Push-Up

• Run

Scaling Options

Weight Vest: Reduce to 10 lb for both men and women, or remove the vest entirely for newer athletes or those with shoulder/back limitations. Run: Substitute 800m run or 1000m row/ski erg as the buy-in if running is limited. Push-Ups: Scale to knee push-ups or elevated push-ups on a box — maintain a rigid plank position. Wall Ball: Reduce load to 14/10 lb and lower target to 9/8 ft; substitute goblet squats if wall ball is unavailable. Sit-Ups: Reduce to 20 per round or substitute banded GHD sit-ups or V-ups. Rep Scheme: Reduce to 10 push-ups / 8 wall balls / 20 sit-ups per round to maintain movement quality and keep athletes cycling smoothly.

Scaling Explanation

Scale the vest if you cannot complete the mile run in under 12 minutes while wearing it, or if your push-up mechanics break down significantly (sagging hips, flared elbows) within the first round. Remove the vest entirely if you are newer than 6 months of consistent CrossFit training — the added load changes every movement pattern and increases injury risk when fatigue sets in. Prioritize technique over load: a clean push-up with no vest is far more valuable than a sloppy one with 20 lbs. The goal is to complete 4+ full rounds in the AMRAP after the run. If you're finishing fewer than 3 rounds, reduce reps or remove the vest next time. Intensity here means sustained effort — not redlining. Athletes should feel challenged but never desperate.

Intended Stimulus

This is a long-duration grind — expect 30-45+ minutes of sustained effort wearing a weight vest. The mile run buy-in sets the tone: this is not a sprint. The AMRAP that follows demands a steady, repeatable engine across three high-rep, cyclical movements. The vest adds constant load stress to every movement, including the run, making this a true test of aerobic capacity, muscular endurance, and mental toughness. Primary challenge is mental — staying disciplined on pacing when fatigue accumulates and the vest starts to feel like a second person on your back.

Coach Insight

Run the mile at a conversational pace — this is not a time trial. Your goal is to arrive at the AMRAP with enough gas to move consistently for 15 minutes. In the AMRAP, establish a sustainable rhythm immediately and protect it. Push-ups will be the first movement to degrade under the vest — break them early (sets of 6-6 or 4-4-4) rather than grinding to failure and stalling. Wall balls demand hip drive; let your legs do the work and keep your chest tall so the vest doesn't cave you forward. Sit-ups are your 'rest' movement — breathe here and use the anchor of your feet to maintain rhythm. Aim for unbroken sit-ups every round. Common mistakes: going out too hot on the run, doing push-ups to failure in round one, and letting the vest pull your torso forward on wall balls causing missed reps or no-reps at the target. Count your rounds carefully — total reps are your score, so every rep matters.

Benchmark Notes

A 1-mile run, then a 15-minute AMRAP of 12 push-ups, 10 wall balls and 28 sit-ups, all in a 20/14 lb vest; the score is reps in the AMRAP (50 a round). L5 (300-350) takes about 2:10 a round. Elite athletes hold about 70 seconds a round (600+); the sit-ups set the floor.

Modality Profile

4 movements total: Push-Up (G), Sit-Up (G), Run (M), Wall Ball (W). Gymnastics = 2/4 = 50%, Monostructural = 1/4 = 25%, Weightlifting = 1/4 = 25%.
