Training in Heat Without Wrecking the Session
The problem
Summer sessions fall apart. Same programme, same sleep, same food — but you're gassed two sets early, the commute leaves you soaked, and the whole day starts on the back foot.
Why it keeps happening
Endurance and strength output both drop as core temperature climbs, because your body starts prioritising cooling over performance: blood diverts to the skin, heart rate rises for the same effort, and perceived exertion goes up before anything else does. Sweat only cools you if it can evaporate — in still, humid air, it can't.
The fix
Airflow restores evaporation. A handheld turbo fan on your face and neck during rest periods drops perceived exertion fast, which is exactly when you decide whether to do the next set.
Use it between sets, not during
Thirty to sixty seconds on the face, neck and inner forearms during each rest — those are the fastest heat-exchange sites. On the commute, aim it at the neck rather than the face. Charge it once a week and keep it in the gym bag, not the drawer.
What to expect
Same session, lower heart rate at the same load, and one or two more quality sets before form goes. In the heat, that's the whole margin.
