Body Tip To improve your workout performance, hold on to your water bottle. Keeping your hands cool may help you exercise longer.
Chill out for a better workout. A small new study from Stanford University School of Medicine found that obese women were able to exercise for longer when they held onto chilling devices. The reason: Body fat is a great insulator, which means people with large amounts of it can overheat quickly during exercise. Keeping their hands cool helped prevent heat-related fatigue and discomfort. Even if you’re not overweight, keeping your hands cool may still keep you going for longer, especially if you wilt easily in the heat. If clasping a cold water bottle sounds like more trouble than it’s worth, you can also invest in cooling devices, like the Cool Point or BEX Runner, that you Velcro around your hands.
