The CrossFit Athlete's Guide to Injury Prevention: Ankle
Number 5: Ankle — and how to train smart enough to avoid them.
CrossFit is one of the most demanding training formats on the planet. It combines Olympic weightlifting, gymnastics, metabolic conditioning, and competitive intensity — often in the same session. It's also one of the most rewarding. But with high demand comes high injury risk, especially when training load, technique, or recovery aren't managed well.
The good news? Most CrossFit injuries are preventable. At Reforge Physio, we work with CrossFit athletes every day — and we see the same patterns come up again and again. This guide breaks down the five most common injury risks in CrossFit and gives you practical, evidence-based strategies to train smarter and stay on the floor.
5. Achilles and calf injuries
The Achilles tendon is a powerhouse — and a common casualty of poor load management. CrossFit's combination of running, jumping, box jumps, and double-unders creates significant cumulative load through the calf-Achilles complex. Achilles tendinopathy and calf strains are two of the most common issues we treat at Reforge.
Why it happens
• Sudden increases in running or jumping volume (especially after rest periods)
• Inadequate calf strength relative to training demands
• Returning to training too quickly after a previous calf strain
• Stiff ankles limiting load absorption and increasing tendon stress
How to train smart
• Load the calf progressively — heavy slow calf raises are one of the best rehab and prevention tools available
• Warm up the Achilles before box jumps and running: light jogging, heel raises, ankle circles
• Monitor soreness after sessions — Achilles pain that lingers more than 24 hours after training is a warning sign
• Address ankle mobility to improve load absorption
Reforge tip
Achilles tendinopathy is one of the most mismanaged injuries in sport — and one of the most successfully treated conditions we see. Early intervention with a structured loading program produces excellent outcomes. Don't wait until it stops you training completely.
