Heated fitness classes or other heated workouts are a common fitness trend. Hot workouts can vary from class to class, ranging from temperatures in the upper 70s to temperatures close to 105 degrees. Humidity and ventilation during classes can also vary between classes, which can range from yoga, barre and Pilates, to strength, core and aerobic-focused classes.
Although a range of different benefits may be promoted for a heated class, research on the benefits of engaging in exercise in warmer temperature is limited and might not be as health promoting as you think. Engaging in exercise in a heated environment does make the workout harder and put more work on your body, which in turn can increase the calorie expenditure. Additionally, heat can make your muscles seem more flexible giving your body a sense of looseness.
Engaging in workouts in hot environments can help individuals focus on increasing endurance performance in the heat (i.e. athlete working to acclimate to working out in a hot environment). However, for most adults there may not be many health benefits associated with heated workouts.
If you do chose to engage in exercise in hot environments, follow these tips:
- Stay hydrated before, during and after class.
- Pregnant individuals and individuals with heart or lung complications should avoid high temperature workouts.
- Listen to your body, stop and slow down as you need to.
- Bring a towel.
- Talk with your healthcare provider if you are new to exercise or new to heated workouts.
