You're committed to your training. You've got a session scheduled. You feel off — a scratchy throat, some fatigue, maybe a runny nose. Do you go? This is a question every boxer faces, and the answer is more nuanced than "push through" or "always rest."
The Neck Rule
Sports medicine practitioners commonly use the "neck rule" as a first-pass guide:
- Symptoms above the neck (runny nose, mild sore throat, nasal congestion, sneezing): Light training is generally acceptable if you feel you can manage it. Reduce intensity, don't push hard, stay well-hydrated.
- Symptoms below the neck (chest tightness, body aches, stomach upset, diarrhoea) or fever: Rest. Training with these symptoms can prolong illness, cause cardiac stress, and risks spreading illness to gym partners.
This rule is a starting point, not an absolute — use judgment alongside it.
Fever: Always Rest
Exercise with fever increases core body temperature further, elevating the risk of cardiac complications and significantly extending recovery time. Never train with a fever above 37.8°C. Wait until you've been fever-free for 24 hours before returning to training.
The Gym Social Contract
If you're contagious, training is disrespectful to your training partners. Symptoms that suggest active infection — productive cough, fever, significant nasal discharge — mean you should stay home regardless of how you personally feel about training. Your training partners have their own health to protect.
When Returning After Illness
Return at reduced intensity. The temptation is to make up for missed sessions by training hard immediately upon recovery — this extends the recovery period, not shortens it. First session back: 50–60% intensity. Second session: 70–80%. Full intensity from session 3 onwards if feeling fully recovered.
What You Can Do When Sick
If you can't train at the gym but want to do something:
- Slow shadow boxing at 30% intensity — maintaining movement patterns without cardiovascular load
- Gentle stretching and mobility work
- Video study of technique — watching high-quality boxing and visualising technique is proven to maintain skill memory
Mental training is legitimate training. Reviewing combinations, watching technique clips, and visualising movement patterns contribute to skill maintenance even during physical rest.
Prevention
Gym equipment, particularly shared gloves, are vectors for viral transmission. If your gym uses shared equipment, request that it be wiped down before and after use. Bringing your own gloves and wraps (the primary contact surfaces) significantly reduces transmission risk.
