Heat exposure
Participants will exercise at home while wearing a clothing ensemble over 19 one hour sessions. They will use validated perceptual scales to guide their effort and thermal sensation.

Control group
Participants will exercise at home over 19 one hour sessions. They will use heart rate to guide their effort. The exercise will take place in cool conditions

About This Trial
Heat acclimation is when you repeatedly exposure yourself to heat so that your body adapts and better tolerates heat. This project will determine if completing a heat acclimation maintenance period after heat acclimation is more beneficial than heat acclimating alone for exercise performance in the heat. To determine this, participants will exercise in the heat before heat acclimation, after heat acclimation, and after heat acclimation maintenance. Researchers will assess the heart's pumping capacity, blood volume, body temperature, and exercise performance to determine which approach is more effective.
