Workout Description

Why This Workout Is Medium

EMOM structure provides built-in recovery (40-50 seconds rest per minute), which is the key mitigating factor. While the workout includes moderate loads (50/35 lb DBs, 24/20 in box), moderate volume (64 double-unders, 40 box jumps, 48-64 calories, 56 snatches), and mixed demands, the forced pacing prevents continuous fatigue accumulation. Average athletes can complete as prescribed, though some may need to scale weights or reps. Total time ~16 minutes with adequate recovery makes this accessible but still challenging.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): Repeated rounds of moderate-rep movements (40 DUs, 10 box jumps, 12/10 cal, 14 snatches) test muscular endurance across upper body, lower body, and grip over 16 minutes.
• Speed (8/10): EMOM format demands quick movement cycling and minimal transition time to maximize reps within each minute. Speed of execution directly impacts total score across all four movements.
• Endurance (7/10): 16 minutes of continuous work with minimal rest between movements demands sustained cardiovascular output. The assault bike and double-unders drive aerobic demand, though EMOM structure provides brief recovery windows.
• Power (7/10): Box jumps and dumbbell snatches are inherently explosive movements. Double-unders require rapid cycling. Power is a primary demand, though fatigue accumulation may reduce explosiveness over rounds.
• Strength (4/10): Moderate loads (50/35 lb dumbbells) and bodyweight movements don't demand maximal strength. Box jumps and snatches require some force production but aren't heavy enough for significant strength stimulus.
• Flexibility (4/10): Double-unders, box jumps, and dumbbell snatches require moderate shoulder and hip mobility. Overhead position in snatches demands some range of motion but not extreme.

Movements

• Double-Under
• Box Jump
• Air Bike
• Alternating Dumbbell Snatch

Scaling Options

Double-Unders: Scale to 60-80 single-unders, or 20-25 double-unders if still developing the skill. Athletes newer to double-unders can also do 20 attempts (misses count) to keep the time cap honest. Box Jumps: Reduce box height to 20/16 inches, or substitute step-ups at the same height for athletes with knee concerns or limited jumping capacity — keep the same rep count of 10. Assault Bike: Scale calories to 8/6 for athletes who struggle to complete 12/10 within 45 seconds, or substitute 14/12 calories on a rower or 200m ski erg. Dumbbell Snatches: Reduce load to 35/20 lbs for intermediate athletes or 25/15 lbs for beginners. Athletes with shoulder limitations can substitute 14 dumbbell deadlifts or kettlebell swings at an appropriate load. Volume scaling: Newer athletes can reduce to a 12-minute EMOM (3 rounds) to manage total fatigue while still experiencing the intended stimulus.

Scaling Explanation

Scale this workout if you cannot complete the double-unders in under 45 seconds consistently, if the Assault Bike calories take more than 50 seconds, or if your dumbbell snatch technique breaks down under fatigue — particularly if you're losing the overhead lockout or hyperextending your lower back. The priority here is maintaining intensity and rest windows, not hitting Rx numbers. If you're finishing each minute with less than 5 seconds of rest, the stimulus shifts from aerobic conditioning to survival mode, which defeats the purpose. Athletes should prioritize technique on the snatch above all else — a sloppy overhead movement under fatigue is a shoulder injury waiting to happen. The goal is to finish each of the 16 minutes feeling challenged but in control, with output staying consistent from round 1 to round 4. If your round 4 times are dramatically slower than round 1, you went out too hard or need to scale the load or reps.

Intended Stimulus

This is a moderate-intensity cyclical EMOM designed to build aerobic capacity and work efficiency across four distinct movement patterns. The 16-minute time domain targets your aerobic engine with repeated short bursts of effort — think hard, sustained effort that never fully lets you recover. Each minute should feel like a controlled sprint where you're working at 80-85% effort, not redlining, but never coasting. The primary challenge is managing fatigue accumulation across four rounds while maintaining movement quality on skill-dependent movements like double-unders and dumbbell snatches. The rotating nature of the EMOM provides just enough active rest to keep output high, making this a potent conditioning piece with a secondary skill and coordination demand.

Coach Insight

The key to this workout is pacing the Assault Bike and double-unders — these two movements will dictate how much rest you actually get. On the double-unders, aim to complete all 40 in one or two sets max; tripping up and restarting eats into your rest window fast. Stay relaxed in your shoulders and use small, consistent wrist circles rather than big arm swings. On the box jumps, use a steady, rhythmic pace — step down rather than jumping down if your legs start to fatigue in rounds 3 and 4 to protect your Achilles and conserve energy. For the Assault Bike, find a sustainable damper setting (typically 4-6) and drive with both arms and legs from the first stroke — don't sprint and die. On dumbbell snatches, alternate arms each rep and keep the dumbbell close to your body on the way up, finishing with a locked-out elbow overhead. Common mistakes: going too hard on the bike in round 1 and losing rest time in rounds 3-4, breaking double-unders into too many small sets, and rushing the snatch lockout. Target at least 10-15 seconds of rest per minute — if you're finishing with less than 5 seconds, you're going too hard or need to scale.

Benchmark Notes

The primary limiters are double-unders (skill bottleneck for beginners) and the assault bike calories (conditioning demand). L5 completes all 4 rounds cleanly (272 total) but may miss a few reps on DUs or bike in later rounds, landing around 240. Elite athletes complete all reps every minute with time to spare, achieving the full 272.
