The pulse raiser should be adjusted such that the workout intensity increases throughout three to five minutes or more. You should feel warm and eager to work out at the end of the pulse raiser. If you stop moving, get cold, or feel like you can't go on, then adjust the settings again. After a pulse raiser, you should still feel warm. However, if you went too hard and your body temperature drops, use the cool-down timer as well as the cooling mats to help bring it back up. You can also use water-based products such as spritzes or sprays to keep yourself warm during exercise. These products will evaporate quickly, so use enough for its stated amount of time. Avoid using alcohol based products as they may cause liver damage if used incorrectly. If you do not feel warm after a pulse raiser, then you may need to increase the duration or intensity of your workouts. There are several factors that may affect how you feel after a pulse raiser including your age, weight, fitness level, environment, and technique.
