Top 3 limiters
The biggest reasons athletes are slow at this station. Fix these in order.
Sandbag too low
A bag sliding down to the lower back forces forward lean and crushes the lower back. Position the bag high on the traps and grip it like a back squat.
Strides too long
Long strides feel powerful but burn quads inside 20 reps. Keep strides just past hip-width — short and clean.
Driving through the toes
Front-foot drive must come from the heel. Toe drive shifts load to quads only and skips glutes — twice the local fatigue, half the propulsion.
Key sessions
The 4 sessions that build sandbag lunges fitness most efficiently. Layer these into the recommended training plan below — at minimum one per week.
Sandbag lunge volume
25 minAfter warm-up: 2×100 m sandbag lunges (20 kg M / 10 kg W) with 3 min rest between. Track total time and reps fallen out. Targets the specific quad-fatigue of station 7.
Lower-body strength
60 minBack squat 4×5 @ 80%, Romanian deadlift 4×6, walking lunges 3×16 with dumbbells, single-leg calf raises 3×12. Builds the unit-strength that makes sled push and lunges feel light.
Station-specific strength
55 minTrap-bar carries 4×30 m, heavy sled drag 4×25 m at 1.5× race weight, walking lunges with sandbag 3×60 m, weighted plank 3×60 s. Targets the exact muscle groups that fail in the back half of Hyrox.
Compromised running circuit
45-55 minAfter warm-up, 3 rounds: 1 km run at goal pace, 50 wall balls (6 kg M / 4 kg W), 200 m sandbag lunges (10 kg). Teaches your legs how to run on a fatigued posterior chain.
Drill tips
10-rep clusters
100 m is ~70 lunges. Break it mentally into 7 clusters of 10 — counting to 70 is a slog, counting to 10 seven times is doable.
Reset only at lane lines
If you stop, stop at a lane line — never mid-stride. Restarting from a known landmark saves seconds and avoids no-reps.
Train at race weight
20 kg M / 10 kg W Open. Lighter bags don't load the spinal erectors enough to transfer.
Common no-reps
- Back knee not touching floor
- Feet passing each other (must be true walking lunges)
Combine with these training plans
The plans below already weave the key sessions into a balanced week-by-week build. Pick the one that matches your goal time or schedule.
12-Week Hyrox Training Plan
The complete 12-week build to a Hyrox race. The longest plan most amateurs benefit from — anything more becomes diminishing returns.
Sub-1:30 Hyrox Training Plan
Break 1 hour 30 minutes — top 25-30% of Open Men. The first true 'good time' threshold most Hyrox athletes target.
Sub-1:30 Hyrox Training Plan for Women
Break 1 hour 30 minutes for Open Women — top 15% globally. The competitive 'good time' threshold for Hyrox women.
