Question: I’m stuck on the trainer all winter due to cold temperatures and early darkness. I can handle the boredom by watching videos, but I have problems with heat buildup. There’s a pool of sweat under the trainer after 30 minutes and my heart rate skyrockets. I open a window but it’s not enough. What’s the solution? — Samantha P.
Coach Fred Matheny Replies: The increased heart rate you experience is calledcardiac drift. It’s a natural reaction to overheating. Your heart has to work harder to cool the body, so heart rate rises even when effort stays steady.
There are two solutions to your problem.
First, get a big fan. Position it about 5 feet in front of your face. Turn it up so you can feel the airflow. If your workout area is arranged so you can put the fan in front of the open window, that’s even better. And see if you can open two windows for cross ventilation.
Second, hydrate well. Have a cold bottle of sports drink or water available at all times. You should be drinking at least one bottle per hour on the trainer and maybe more, depending on how much you’re sweating. Cold fluid will keep you hydrated and help lower your internal temperature. Put ice in your drink so it’ll be cold for the hottest part of the workout.
If you use these suggestions, I bet you’ll be able to train longer and harder with more comfort.
