The defining factor is the 400m D-ball carry at 90# as a finisher — brutal even fresh, but coming after 450m of prior carries and 600m of sprinting, it's nearly crushing. D-ball carries compress the chest and restrict breathing, making the sprint intervals uniquely punishing. Cumulative core, leg, and respiratory fatigue compound across three distinct sections, with no built-in rest. Most average athletes will need multiple breaks on the final 400m carry.
This workout develops the following fitness attributes:
4 total movements: Sprint and Run are Monostructural (2/4 = 50%); D-Ball Ground to Shoulder and Farmer Carry are Weightlifting with external load (2/4 = 50%). No Gymnastics movements present.
| Attribute | Score | Explanation |
|---|---|---|
| Endurance | 7/10 | Repeated carry-sprint combinations and a final 400m run create sustained cardiovascular demand. The total volume and mixed locomotion challenge aerobic capacity significantly beyond moderate levels. |
| Stamina | 8/10 | The 400m d-ball carry is a brutal test of sustained muscular output. Grip, core bracing, and leg drive are taxed continuously across multiple heavy carry segments with minimal true recovery. |
| Strength | 5/10 | A 90# d-ball requires meaningful strength to pick up and stabilize, especially under fatigue. However, this is a carry-based stimulus, not maximal force production, placing it squarely at moderate strength demand. |
| Flexibility | 3/10 | D-ball bear-hug positioning demands some thoracic extension and shoulder openness. Sprinting requires basic hip flexor mobility. No extreme range of motion requirements throughout the workout. |
| Power | 4/10 | Sprint transitions after heavy carries demand explosive leg turnover, and d-ball pickups require hip extension power. However, the dominant stimulus is a sustained grind rather than purely explosive effort. |
| Speed | 5/10 | Sprint segments provide genuine speed stimulus, but heavy carry fatigue blunts top-end velocity. Transitions between carry and sprint require quick mental and physical shifts, creating a moderate speed demand. |
