Sandbag lunges drill.

Front-rack sandbag walking lunges, the most underprepared station in the race. Front-rack position is unfamiliar, posture failure cascades to the next station, and the running afterward exposes whatever you skipped in training.

Technique cues

Four cues that fix most issues.

Open this page mid-session. Cycle through the cues across reps. Don't try to fix all four in one set, pick one, dial it, then add the next.

Front-rack high, ribs down

Sandbag sits high on the front delts and biceps shelf. Ribs stay tucked. Don't let the sandbag pull you into hyperextension, that's where the back goes.

Knee tracks over middle toes

Lunging knee tracks straight over the second toe. Knee caving in = glute weakness. Externally rotate slightly to fix.

Step length: short and controlled

Stride too long = front shin angles back, posterior chain doesn't load right. Short steps, deliberate descent.

Back knee taps but doesn't slam

Light tap on the floor with the back knee. Slamming jars the spine and you'll feel it 50 m later.

Common faults

What it looks like when it's going wrong.

Each fault has a diagnostic. The diagnostic tells you what to change, load, posture, cadence, rest interval, or skill cue.

Sandbag sliding down chest

Repositioning mid-walk costs 20+ seconds total. Set it high in the warm-up and lock the front-rack.

Forward lean increasing

Core has fatigued. Glute bridges + planks in your warm-up routine address this.

Knee pain on descent

Step is too long, or quad is dominating. Shorter step, more glute, slower tempo.

Grip fading before legs

Front-rack grip is undertrained. Add farmer carries + dead hangs.

Modifications

If equipment, injury or level is the constraint.

Substitutes that train similar capacity. None are perfect mirrors, most are 80-90% of the demand. That's enough for week-to-week progress.

No sandbag

Heavy plate or kettlebell held in goblet position. Same posture demands.

Low back issues

Goblet lunge instead of front-rack. Less spinal load.

Knee issues

Reverse lunges. Same conditioning, less knee stress on descent.

Suggested rep scheme: 4 × 20 m walking lunges at training load (start at 75% of race load). 60s rest. Build to 100 m unbroken at race load over 6-8 weeks.
