Loaded Carry & Sled
CARRY + DRAG · BOTH PATHS
CARRY + DRAG · BOTH PATHS
Why it matters · Operator Carrying and dragging heavy load is the most honest conditioning there is, and the closest gym analog to moving a casualty or a load of gear. The farmer's and suitcase carries build grip and anti-lateral-flexion strength; the sled push and drag build leg drive and brutal conditioning with no eccentric and almost no soreness, so you can train them hard and recover fast.
Why it matters · Longevity Grip strength is one of the most reliable predictors of all-cause mortality in the literature, and loaded carries build it relentlessly, along with bone density and posterior-chain endurance. The sled's all-concentric work lets an older or banged-up trainee get a hard conditioning effect with minimal joint stress and next to no muscle damage.
Form cues
- Carry: stand tall, shoulders packed, ribs down; walk with controlled, even steps
- Suitcase carry: load one side, resist the lean, keep both shoulders level
- Sled push: low body angle, arms long, drive through the legs with powerful steps
- Sled drag: lean back against the load, pull hand over hand or walk it backward
- Set carries down under control; keep the back flat on the sled
Common errors
- Leaning away from a suitcase load instead of standing tall and resisting it
- Rounding the back to push a heavy sled (keep a long, braced spine, drive with the legs)
- Turning a strength carry into a jog with short, rushed steps
Path A scaling Start carries with moderate loads for shorter distances, and the sled at a moderate weight for steady pushes and drags. Build distance and load gradually; the sled is a forgiving place to find a hard effort.
Path B scaling Load the carries heavy for distance, and the sled heavy for hard intervals of pushes and drags. Progress both across the blocks; heavy sled work doubles as the Day 4 conditioning when you want it to.
