Single Leg Kettlebell Calf Raise
The single leg kettlebell calf raise targets the gastrocnemius and soleus one leg at a time using kettlebell resistance, correcting calf imbalances and building the running endurance HYROX athletes need across all 8 race segments.
Movement and evidence
A single-leg kettlebell calf raise is loaded ankle plantar flexion performed on one leg while holding a kettlebell. The gastrocnemius and soleus contribute, while balance and grip are additional demands. Research comparing standing and seated bilateral training does not prove kettlebell superiority or HYROX® transfer.

Execution
Use stable support when needed, control the rise and descent and choose a tolerable range. Load, repetitions and whether to use a step depend on balance, equipment and goal. Equal repetitions do not prove a corrected imbalance; stop for acute or worsening pain.
