High-volume bodyweight work (approx. 650 total reps) with compounding fatigue across push-ups, core, and legs. No external load or advanced skills, but the duration typically runs 25–45 minutes for most athletes. The challenge is sustained pacing, muscular endurance, and maintaining movement standards under fatigue.
Scaling suggestions available
Large bodyweight volume and 80 burpees create sustained fatigue, but movements are basic-to-moderate skill and the only external load is a standard kettlebell swing. Most athletes will live in a steady, aerobic grind for 20–30 minutes. The lack of heavy loading and high-skill gymnastics keeps the overall challenge in the medium range.

High-volume chipper with 500 total reps across mixed modalities. Most athletes finish in 20–35 minutes if appropriately scaled, but cumulative fatigue, grip demands, midline fatigue, and breathing work make it challenging. Loads are light, yet cycle speed, transitions, and skill elements (double-unders, knees-to-elbows) raise the difficulty. Proper pacing and smart partitioning of big sets are crucial.

Angie is 400 unpartitioned bodyweight reps. Using the framework: work density = (400 × 0.5) ÷ ~25 min ≈ 8 units/min (low). Movement complexity averages mostly basic movements with one moderate element (pull-up). Time domain typically lands in the 20–30 minute range. No modifiers apply. Combined, this maps to a Medium rating, despite the grindy muscular endurance feel.

Bert is a long, high-volume bodyweight chipper with six 400m runs interspersed between big sets of burpees, push-ups, lunges, and squats. While the movements are simple, the sheer volume, repeated interference of similar patterns, and duration (often 50–70 minutes for average athletes) create major muscular stamina and aerobic demands. Pacing, mental toughness, and strict movement standards make this a very challenging test.

This chipper mixes 300 total reps with mostly bodyweight and light loading, producing relatively low work density but steady fatigue. Movement complexity averages moderate with a few advanced skills (double-unders, knees-to-elbows, burpees). The expected 20–30 minute time domain keeps heart rate elevated while requiring sustainable pacing. Overall, it challenges stamina and coordination without heavy strength demands, fitting a solid medium difficulty.
Scaling suggestions available
Low work density with roughly 100 basic bodyweight reps plus a short 500 m row. Movement complexity is mostly basic (air squat, push-up, sit-up, row) with only one moderate-skill piece (pull-up). The time domain is short for most athletes and there’s no external loading. Overall this maps to an Easy score (~20) in the provided framework.
Scaling suggestions available
Massive volume (600 total reps) with 300 burpees intertwined with 300 dumbbell reps at 50/35 lb drives long duration and cumulative fatigue. Movement variety taxes shoulders, hips, and midline, while man makers and strict presses significantly slow pace. Expect 50–90 minutes for most, demanding relentless pacing, grip/shoulder stamina, and high mental resilience.

Fatal 40 is a massive chipper: 5.6 km of total running with 520 mixed reps across barbell, gymnastics, and odd-object work. Work density stays low because of the long duration, but complexity averages moderate with high-skill snatches and advanced elements like toes-to-bar and double-unders. Heavy loaded volume (200 reps) increases difficulty. Expect a grindy, endurance-first effort with serious grip and midline taxation.
Scaling suggestions available
Huge volume (480 total reps) with 240 loaded reps (kettlebell swings and clusters) and long effort in the 30–40 minute window makes this a grind. Movement complexity averages moderate-high due to the cluster. Work density is modest per minute, but the heavy-volume modifier applies, pushing it into the Hard range for most athletes.
Scaling suggestions available
A long chipper with eight 400m runs (2 miles total) and seven demanding sets of 20, including heavy deadlifts, technical overhead squats, and chest-to-bar pull-ups. The combination of volume, heavy loading, grip fatigue, and sustained pacing pushes most athletes beyond 35 minutes, often past 45 minutes, making it an extremely challenging test of endurance and stamina.

The Don is a high-volume, long-duration chipper: 10 movements with 66 reps each (660 total). While loads are moderate to light, cumulative fatigue, grip demand, and repeated hip hinge/pulling make it punishing. Expect 45–90 minutes for most, with significant pacing and strategy required to avoid early redline and excessive rest later.
