KEReviewing SPC Kerns’ Sprint-Drag-Carry (SDC) and run form — breaking it down from a military fitness coach perspective.
I’m seeing a lot of criticism online… but not a lot of actual coaching. So here’s what matters 👇
Main issues:
• Overstriding → foot landing in front of the body = braking each step
• Heel striking → loss of speed and efficiency
• Vertical bounce → energy going up instead of forward
• Wide arm swing → torso rotation + wasted energy
These are the exact mistakes that slow down your Sprint-Drag-Carry time and 2-mile run performance on the Army Fitness Test (AFT).
What we want instead:
• Short, quick steps
• Foot strike under hips
• Slight forward lean
• Arms driving straight forward/back
SDC breakdown:
• Drag (90 lbs Normally) → quad-dominant, requires strength + endurance
• Lateral shuffle → stay low, don’t cross feet, build momentum
• Farmer carry → strong position, but heel striking still slows you down
• Final sprint → same inefficiencies = lost time
If you’re training for the Army Fitness Test, your workouts need to be structured — not random.
I coach athletes to improve their AFT scores with custom built programs built around your weaknesses.
This is how you turn effort into results. Comment coach to work 1-1 with me or follow my IG and I’ll send you a DM with the Free AFT fitness APP.
