Workout Description

Why This Workout Is Medium

13 rounds sounds daunting, but each round is short and varied with natural micro-breaks (18-sec hollow hold acts as active rest). Deadlifts at 1.5x bodyweight are moderate for average CrossFitters with only 2 reps. Double-unders and push-ups are manageable in small doses. The limiting factor is cumulative grip fatigue from deadlifts plus row, but low rep counts prevent true failure. Estimated 20-30 minutes total.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): High round count with push-ups, double-unders, hollow rock holds, and rowing accumulates significant muscular endurance demand. Upper body and core fatigue compounds across 13 rounds of continuous output.
• Endurance (7/10): Thirteen rounds of rowing and double-unders create sustained cardiovascular demand throughout. The repeated aerobic cycling across all movements keeps heart rate elevated for the workout's duration.
• Speed (6/10): For-time format across 13 rounds incentivizes fast transitions and efficient cycling. Double-unders and rowing reward quick turnover, and minimizing rest between movements is critical for a competitive finish time.
• Strength (5/10): Deadlifts at 1.5 bodyweight provide a moderate strength stimulus, but only 2 reps per round limits maximal strength development. The load is meaningful but not near maximal effort territory.
• Power (4/10): Double-unders require rhythmic wrist and calf power, and deadlifts at 1.5 bodyweight can be performed explosively. However, the low rep count and mixed modalities reduce overall power emphasis significantly.
• Flexibility (3/10): Hollow rock holds require posterior chain and hip flexor awareness, while deadlifts need basic hamstring mobility. Overall range of motion demands are moderate and accessible for most athletes.

Scaling Options

Deadlift weight: Scale to 1x bodyweight or a load you can confidently lift for 2 crisp reps every round without form breakdown. If 1.5x BW is your 5RM or heavier, drop to 50-60% of that. Push-ups: Scale to knee push-ups or elevate hands on a box to maintain full range of motion and unbroken sets. Double-unders: Sub 40 single-unders, or 10 attempts at double-unders with a 40-single-under cap per round. Alternatively, 10 double-unders if still developing the skill. Hollow rock hold: Scale to a hollow body hold (static, no rocking) or reduce to 12 seconds if midline fatigue causes form to collapse. Rounds: Reduce to 10 rounds if the 13-round volume feels excessive for your current fitness level, keeping the same rep scheme to preserve the stimulus.

Scaling Explanation

Scale the deadlift if 1.5x bodyweight represents more than 70-75% of your 1RM, or if you cannot maintain a neutral spine for both reps every round. Two reps should never feel like a grind — they should feel heavy but controlled. Scale push-ups if you cannot complete 8 unbroken reps in round 1 with full range of motion; breaking push-ups into multiple sets early signals the load is too high for the intended stimulus. Scale double-unders if you're spending more than 60-90 seconds on them per round — excessive time here destroys the workout's flow and shifts the stimulus away from conditioning. The target completion time is 18-28 minutes. If you finish under 16 minutes, the deadlift weight was likely too light or the double-unders were subbed too aggressively. If you're projected over 30 minutes, reduce rounds to 10. Prioritize technique on the deadlift above all else — intensity is secondary to moving safely under load across 13 rounds.

Intended Stimulus

This is a moderate time domain workout targeting 18-28 minutes of sustained, cyclical effort. The stimulus is a hard, steady engine — not a sprint, but never comfortable. With 13 rounds of mixed movers, the goal is to build aerobic capacity while managing a strength element (heavy deadlifts) and a skill element (double-unders) under fatigue. The primary challenge is mental and conditioning-based: staying disciplined across 13 rounds when the temptation is to either go out too hot or mentally check out mid-workout. The hollow rock hold at the end of each round acts as a forced reset, building midline endurance and body awareness under accumulated fatigue.

Coach Insight

Treat this as a 13-round time trial, not a race. Your round 1 pace should feel almost too easy — if you're breathing hard after round 3, you went out too fast. On the row, aim for a consistent, moderate damper setting and avoid spiking your heart rate; 155 meters should take roughly 35-45 seconds at a controlled pace. Deadlifts at 1.5x bodyweight are heavy — set up with intention every single rep. Hinge, brace, and pull. Do NOT rush the setup just because it's only 2 reps; a sloppy deadlift under fatigue is how injuries happen. Push-ups should stay unbroken for most athletes — if you're breaking them, that's a scaling signal. For double-unders, find your rhythm quickly and don't panic if you trip; take a breath and restart calmly. The hollow rock hold is your active recovery — use it to control your breathing and reset your midline before the next row. Common mistakes: going too fast on the row in early rounds, rushing deadlift setup, and letting the hollow rock hold become sloppy (hips dropping, arms drifting). Lock in your hollow position — ribs down, lower back pressed to the floor, arms overhead.

Benchmark Notes

13 rounds of a 155 m row, 2 deadlifts at 1.5x bodyweight, 8 push-ups, 20 double-unders and an 18-second hollow-rock hold. The hold and row set a floor of about 50 seconds a round. L5 (28:30-31:30) takes about 2:20 a round. L10 (under 20 min) holds about 90 seconds a round.

Modality Profile

5 movements total: Push-Up (G), Double-Under (G), Hollow Rock (G) = 3 Gymnastics; Row (M) = 1 Monostructural; Deadlift (W) = 1 Weightlifting. Percentages: G = 3/5 = 60%, M = 1/5 = 20%, W = 1/5 = 20%. Rounded: G: 60, M: 20, W: 20.
