Workout Description

Why This Workout Is Medium

This workout combines moderate aerobic demand (2.1km total running) with manageable strength-endurance work. The 700m runs provide natural recovery between rounds, breaking up fatigue accumulation. DB step-ups and push-ups are fundamental movements at reasonable volumes (48 total reps each). The dumbbell load is light-moderate, and the continuous-but-broken structure prevents the relentless fatigue of true high-intensity work. Average athletes complete this as prescribed in 20-25 minutes with manageable pacing.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): 48 total push-ups and 48 total step-ups across three rounds demand significant muscular endurance. The combination of upper body and lower body work creates cumulative fatigue that tests sustained output capacity.
• Endurance (7/10): Three 700m runs provide sustained cardiovascular demand across the workout. The repeated running intervals test aerobic capacity and the ability to maintain effort despite accumulated fatigue from other movements.
• Speed (6/10): For-time format demands consistent pacing and efficient transitions between movements. Quick cycling through push-ups and maintaining running pace are important for minimizing total time.
• Strength (4/10): Moderate dumbbell loads (50/35, 24/20) require some force production, but the primary demand is muscular endurance rather than maximal strength. Push-ups are bodyweight-based strength work.
• Flexibility (3/10): Step-ups require moderate hip and ankle mobility, while push-ups demand shoulder and thoracic mobility. Running requires basic lower body range of motion but nothing extreme.
• Power (2/10): Minimal explosive demand. The workout emphasizes steady-paced grinding rather than quick, powerful movements. Step-ups and push-ups are performed at controlled tempos.

Scaling Options

Reduce DB weight to 35/20 lbs for athletes newer to loaded step ups or those with balance limitations. Lower box height to 20/16 if the standard height compromises knee tracking or stability. Reduce push ups to 20 per round or substitute with knee push ups or hand-elevated push ups on a box to maintain full range of motion. Shorten the run to 500m per round if the full distance will push the workout beyond 35 minutes or if running is a significant limiter. For 2-round options, reduce to 2 rounds total for athletes returning from injury or newer CrossFitters while keeping all other elements intact.

Scaling Explanation

Scale the load if you cannot perform at least 8 unbroken step ups with good single-leg stability and upright torso at Rx weight. Scale push ups if you cannot perform 15+ unbroken strict push ups in a fresh state — broken or snaked reps under fatigue lead to shoulder and lower back strain. The goal is to keep each round feeling similar in quality and time — if round three is dramatically slower or your form collapses, you scaled too aggressively or not enough. Prioritize movement quality over Rx every time. Target completion between 20-28 minutes for most athletes. If you're under 18 minutes, consider increasing load or distance next time.

Intended Stimulus

This is a moderate time domain workout targeting 18-28 minutes of sustained aerobic effort with muscular endurance demands. Expect a hard, steady engine challenge — this isn't a sprint, but you should never feel comfortable. The run serves as both a conditioning driver and active recovery between the DB step ups and push ups. The primary challenge is managing leg fatigue from step ups bleeding into the run, while keeping push ups consistent across all three rounds. Expect your chest, shoulders, and quads to accumulate significant fatigue by round two.

Coach Insight

Run the first 700m at a pace you could sustain for 5k — controlled but honest. Don't blow your legs out early. On step ups, drive through the heel of the working leg and stand fully tall at the top before stepping down. Keep the DB in a neutral hang position rather than racking it, which saves your shoulders for push ups. For push ups, break early rather than grinding to failure — consider sets of 10-8-8-6 or 8x4 to stay crisp. The most common mistake is torching push ups in round one and then crawling through rounds two and three. Lock your core, keep elbows at roughly 45 degrees, and maintain a rigid plank — no snaking or worming reps. Transition quickly off the run into step ups without standing around.

Benchmark Notes

Push-up capacity under accumulated leg fatigue is the primary limiter; 32 reps per round deteriorates fast for most athletes. L5 (~20 min) runs at a steady aerobic pace (~3:30/700m), breaks step-ups once, and manages push-ups in 3-4 sets per round. The 50 lb DB step-up also taxes quads, compounding the run's leg cost.

Modality Profile

Three unique movements across three modalities: Run (Monostructural), Alternating Dumbbell Step Up (Weightlifting), Push-Up (Gymnastics). Equal distribution across modalities results in approximately 33/33/34 split.
