Training in Hot Weather: How to Stay Safe and Keep Performing

Summer in York can catch people off guard.

One minute you’re training in a hoodie, the next the gym feels ten degrees warmer and your usual session suddenly feels harder than expected. Whether you’re lifting, running, doing a HYROX session or jumping into a class, training in hot weather brings a different challenge.

The good news? You don’t need to stop training when it gets warm. You just need to train a little smarter.

Why Training Feels Harder in the Heat

When temperatures rise, your body has to work overtime to cool itself down. Blood flow shifts towards the skin to help regulate temperature, your heart rate climbs quicker, and you’ll usually fatigue faster than normal.

That workout that felt comfortable a few weeks ago? It might suddenly feel much tougher.

And that’s okay.

Hot weather is not the time to chase hero workouts every single day. Sometimes the smartest thing you can do is adjust expectations slightly and focus on consistency.

Hydration Matters More Than You Think

If you’re waiting until you feel thirsty, you’re probably already behind.

Most people underestimate how much fluid they lose when training in warmer weather, especially in a busy class environment. Sweating more means losing fluids and electrolytes faster, which can affect performance, recovery and energy levels.

A few simple things can make a big difference:

• Start hydrated. Don’t arrive at the gym already dehydrated from the day.
• Sip water throughout the day rather than trying to drink loads all at once.
• If you’re doing a long session or sweating heavily, consider adding electrolytes.

You don’t need anything fancy. Just being a bit more intentional helps.

Adjust Your Effort

This is a big one.

Training in the heat doesn’t mean pushing through no matter what. It means listening to your body and understanding that pace, weights or intensity may need to shift slightly.

Maybe your normal running pace feels harder. Maybe the barbell moves slower than usual. Maybe you take slightly longer between sets.

That’s not losing fitness. That’s being smart.

The goal is to keep showing up, not to bury yourself every session.

Dress for the Conditions

Seems obvious, but it matters.

Lighter clothing, breathable fabrics and bringing an extra top can make training much more comfortable. And yes, turning up with water is a very good idea.

York doesn’t often get extreme heat, which also means many of us aren’t particularly adapted to it. Give yourself a few sessions to adjust.

Recovery Becomes Even More Important

Hot weather can leave you feeling more drained than usual.

Prioritise sleep, keep food quality high and don’t underestimate the importance of cooling down after sessions. A short walk, getting out of the heat, and replacing fluids can go a long way.

Keep Moving This Summer

The biggest mistake people make during summer is stopping altogether.

Holidays, BBQs, kids being off school, weekends away, sunny evenings - life gets busier. But staying active during summer helps you enjoy all of those things more. More energy. More confidence. More capacity to actually live life outside the gym.

You don’t need perfect training. You just need consistent training.

Train smart, stay hydrated, and keep showing up - even when York decides to surprise us with a heatwave.
