Recommendations for Fighters
- Choose Tier 1 organizations when possible for maximum medical protection
- Get independent medical clearance before fighting, even if the org does not require it
- Invest in hand conditioning before bare knuckle bouts (see strengthen hands)
- Learn proper technique to reduce injury risk (see bare knuckle striking technique)
- Respect mandatory rest periods between fights, even if the org does not enforce them
- Monitor for concussion symptoms for 72 hours after any fight involving head strikes
