Workout Description

Why This Workout Is Very Hard

This workout combines two brutal running segments — a nearly 2km run followed by a 2008m medicine ball run (20/14 lb) — with 173 air squats and 26 wall balls creating massive leg fatigue. The medicine ball run alone is an extreme endurance challenge. Total time likely exceeds 40-50 minutes for average athletes. The cumulative leg destruction from squats, box jumps, and both runs makes this Very Hard.

Training Focus

This workout develops the following fitness attributes:

• Endurance (9/10): Two substantial runs totaling nearly 4km, including a medicine ball carry run, create massive cardiovascular demand. This workout is dominated by aerobic output sustained over a long duration.
• Stamina (8/10): 173 air squats, 26 wall balls, 24 box jumps, and 7 pull-ups accumulate significant muscular endurance demands, especially in the legs and posterior chain across extended effort.
• Speed (4/10): For Time format incentivizes pacing and efficient transitions, but the long runs and high rep counts favor steady aerobic pacing over sprint cycling or fast movement turnover.
• Flexibility (3/10): Box jumps, wall balls, and air squats require adequate hip and ankle mobility. The medicine ball run adds thoracic demand, but nothing extreme is required overall.
• Power (3/10): Box jumps and wall ball shots introduce explosive hip extension, but the sheer volume and fatigue context shift these toward stamina rather than true power expression.
• Strength (2/10): A single deadlift at 65% 1RM is the only true strength element. The remaining movements are bodyweight or light load, making maximal force production a minor component.

Scaling Options

Run distances: Reduce the opening run to 1200-1400m and the medicine ball run to 1200-1400m if the full distances are not feasible in the time cap. Pull-ups: Sub ring rows, banded pull-ups, or jumping pull-ups. Box jumps: Reduce height to 20/16 in or sub step-ups for athletes with knee concerns. Deadlift: Keep at 65% of true 1RM — if no 1RM is established, use a moderate load that feels like a strong single but not a grind (roughly RPE 7-8). Wall balls: Reduce to 14/10 lb or lower the target height. Air squats: Reduce to 100-120 reps if 173 is prohibitive given the athlete's capacity. Medicine ball run: Use a lighter ball (14/10 lb) or substitute a dumbbell carry at a manageable weight.

Scaling Explanation

Scale if you cannot run 1978m in under 12 minutes at a conversational pace, cannot perform at least 3 strict or kipping pull-ups, or if 65% of your deadlift 1RM feels unstable. The goal is to finish this workout in a challenging but sustainable window — ideally 35-55 minutes for most athletes. If the projected time exceeds 60-65 minutes, reduce run distances and rep counts to preserve the intended stimulus of a long, steady aerobic grind. Prioritize technique on the deadlift above all else — it is a single rep, but fatigue from the run makes it deceptively risky. Intensity matters less than consistent movement quality across the full duration of this workout.

Intended Stimulus

This is a commemorative or themed workout — the numbers (1978, 24, 26, 173, 2008) likely reference significant dates or events, giving it a hero or tribute feel. Expect a long, grinding effort in the 30-60+ minute time domain. The stimulus is a long steady engine test — sustained aerobic output with moderate strength and skill demands woven in. The primary challenge is mental: managing fatigue across a long workout with varied movements, especially the two running segments bookending the piece. Athletes should expect to be uncomfortable and must pace intelligently from the very first meter.

Coach Insight

The two runs are your anchors — treat the opening 1978m run as a controlled warm-up pace, not a sprint. You will pay dearly on the 2008m medicine ball run at the end if you go out too hot. The middle section (pull-ups, box jumps, deadlift, wall balls, air squats) is relatively low volume, so move through it with purpose but don't redline. Key tips: (1) The single deadlift at 65% is a gift — set up perfectly, brace hard, and move on; don't overthink it. (2) Break wall balls early if needed — sets of 13/13 or 10/9/7 are fine; unbroken is ideal but not worth a breakdown. (3) Air squats at 173 reps is the hidden monster — break these into manageable sets of 20-30 from the start, never go to failure. (4) The medicine ball run is the real test — hold the ball in a comfortable carry position (chest, shoulder, or alternating) and settle into a pace you can sustain. Common mistakes: sprinting the first run, treating the middle section as rest, and underestimating the air squats before a long weighted run.

Benchmark Notes

A 1,978 m run, 7 pull-ups, 24 box jumps, 1 deadlift at 65% of max, 26 wall balls, 173 air squats and a 2,008 m medicine-ball run at 20/14 lb. The two runs are two-thirds of the time. L5 (31:30-35 min) runs about 5:05 per kilometre, then about 6:00 with the ball. L10 (under 21 min) runs near 3:25 and 4:05.
