7. Sleep Monitors
Sleep may not seem to have a lot to do with exercise. But if you're tired during the day because you didn't sleep well, your performance will be affected.
Some home-based sleep monitors record brain waves via sensors in headbands worn at night. Others measure your movements during sleep.
Few of the devices on the market have been scientifically tested for accuracy. If you often have problems falling or staying asleep, even after you make sleep a priority on your schedule, check in with your doctor.
