Workout Description

Why This Workout Is Very Hard

13 rounds creates brutal cumulative fatigue. The Echo Bike spikes heart rate and taxes the legs, feeding directly into 26 box jump overs — a massive 338 total reps of explosive leg work. The 275/205lb deadlift then demands grip and posterior chain when both are already compromised. Total volume (104 bike cals, 338 BJO, 13 heavy deadlifts) with no built-in rest makes this a significant endurance and strength challenge.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): 338 total box jump overs across 13 rounds heavily taxes leg muscular endurance. Combined with 104 calories on the bike, sustained muscular output is a primary demand of this workout.
• Endurance (7/10): 13 rounds of Echo Bike calories combined with box jump overs creates sustained cardiovascular demand throughout. The repeated cycling efforts accumulate significant aerobic stress over the full workout duration.
• Power (6/10): Box jump overs are inherently explosive, requiring repeated hip extension power. The deadlift singles also demand powerful hip drive. High volume of jumps makes power a consistent and significant demand throughout.
• Speed (6/10): For Time format incentivizes pushing pace on the bike and cycling box jumps efficiently. Minimizing transition time between movements across 13 rounds is critical for a competitive finish time.
• Strength (5/10): 13 singles at 275/205 lb deadlift is a moderate strength stimulus. The load is significant but performed as single reps with rest built in, reducing maximal strength expression under fatigue.
• Flexibility (3/10): Box jump overs require basic hip flexion and landing mechanics. Deadlifts demand standard posterior chain positioning. No extreme mobility requirements exist in this workout beyond functional movement patterns.

Scaling Options

Deadlift: Scale to 225/155 lb (roughly 80% of Rx) for athletes who can't perform a crisp, safe hinge under fatigue, or drop further to 185/135 lb for newer athletes. Box Jump Overs: Reduce to 20/16 in, or substitute step-overs entirely for athletes with Achilles concerns or poor landing mechanics. Reduce reps to 20 per round if 26 feels unmanageable. Echo Bike: Reduce to 6 calories per round for athletes who struggle to maintain consistent output. Volume: Consider 10 rounds instead of 13 to keep the workout under 35 minutes for less-conditioned athletes. The single deadlift per round should remain — it's a key stimulus anchor.

Scaling Explanation

Scale the deadlift if your 1RM is under 315/235 lb — at that point, 275/205 lb under 13 rounds of fatigue becomes a back injury risk, not a training stimulus. Scale the box jump overs to step-overs if you have any Achilles, knee, or landing concerns, or if your jump mechanics deteriorate after round 4. The goal is to keep moving with consistent effort throughout all 13 rounds — if you're stopping for more than 15-20 seconds at any point due to load or volume, scale down. Prioritize technique on the deadlift above all else; a rounded back on a heavy single after 8 rounds of box jumps is how injuries happen. Target finish time is 28-38 minutes — if you're projected to go over 40 minutes, reduce rounds or reps to preserve intensity.

Intended Stimulus

This is a moderate-to-long grind lasting roughly 25-40 minutes for most athletes. The combination of cyclical cardio, high-rep explosive movement, and a heavy barbell creates a relentless aerobic demand with repeated power output. The single deadlift per round is deceptively taxing — it's not about strength, it's about maintaining tension and technique under fatigue. Expect your legs and lungs to be the limiting factor, not the deadlift itself. The primary challenge is mental: 13 rounds is a long time to stay disciplined with pacing and movement quality.

Coach Insight

The key to this workout is treating the Echo Bike as a controlled effort, not a sprint — aim for a sustainable 70-75% output that lets you step off and immediately attack the box jump overs. The 26 box jump overs are the biggest time sink and the place where athletes blow up early. Break them into 2 sets of 13 or 3 sets of 9-9-8 from round one — do NOT go unbroken in early rounds hoping to hang on. Step down off the box every rep to protect your Achilles and conserve energy; this is a long workout. The deadlift is a reset — treat it as a breath, a hinge, and a mental checkpoint. Set your back, brace hard, and pull with intent. Common mistakes: going too hard on the bike in rounds 1-3, doing unbroken box jumps until you can't, and rushing the deadlift setup under fatigue. Transitions should be smooth and deliberate, not frantic.

Benchmark Notes

Thirteen rounds of an 8-calorie Echo bike, 26 box jump-overs and one 275/205-lb deadlift: the 338 box jump-overs set the pace. Even elite athletes need about 70 seconds a round, so L10 starts under 16:30. L5 (30:30-36:00) is about 2:30 a round with the jump-overs broken into sets of 8-10.

Modality Profile

Three movements across all three modalities: Air Bike (Monostructural), Box Jump-Over (Gymnastics), Deadlift (Weightlifting). Each modality gets roughly 33% with Weightlifting rounded to 34%.
