❓ FAQ
Are heel hooks dangerous for training?
Yes — heel hooks have caused serious knee injuries at all levels. Always apply slowly, use a training partner who will tap early, and never apply explosively. Many gyms restrict heel hooks to advanced practitioners.
Which leg lock should a beginner learn first?
Start with the straight ankle lock — it provides a foundation for leg lock mechanics with much lower injury risk. Add heel hooks only after developing mat experience and training with experienced partners.
