Overdress to sweat more quickly. Layer your clothing before you workout, or clean your house. Moving around with too many clothes on is sure to make you hotter faster, which in turn, will make you sweat. Some people enjoy layering up and then going running on warm days because sweating helps you to lose water weight.
Work out your muscles. Weight lifting is an ideal way to work up a quick sweat. Weight lifting is all about pushing your limits with each workout. Once weight lifters become accustomed to a workout, they generally move up in difficulty. Work up a quick sweat by lifting more quickly or by lifting a little heavier than normal. Take care that you don't increase in difficulty too much as you could injure yourself.
Increase your heart rate to sweat more. Get your blood pumping with cardiovascular exercise. Go for a run or ride a bike. Performing sprints is a great way to get a quick sweat as you are exerting yourself to the maximum level for a short period of time, stopping, and exerting yourself again. Try going for a run and running as fast as you can, for as long as you can. Your body heat will rise quickly and you are sure to be drenched in sweat not long after you begin your run.
Turn up the heat. Step outside for a quick jog on a hot or humid day. The extra heat is sure to warm you up more quickly than the warmth of a mild day. If you are stuck indoors, turn the heat on or the air conditioning off and jump on the treadmill for a 10-15 minutes. The added heat will create a definite difference in the amount of sweat that you produce.
Step into a sauna or hot tub. Both of these devices will raise your body temperature and will cause you to start perspiring. You may not notice because you are already wet, but you will begin to sweat. If you don't have access to these, run a hot bath and sit in it for 10 to 15 minutes. Beads of sweat will appear on your forehead. Sweating can be good for you as it helps your body to flush out toxins.
