Does your heartrate really have to increase to lose weight?

Walking, no matter what the pace, will cause your heart rate to increase because even if you aren't doing a heavy work out you are still increasing your heart rate past what it normally would be. Walking or other exercising 30 minutes 3 times a week is usually the best way to go about exercising. When you get used to that, it wouldn't be bad to do that up to 5 days a week. But five days is not a must, and never exercise to the point of pain. I'm probably not telling you anything you don't know, but I hope I am helpful in some way. : )

Hi Im Toya I do quite a lot of exercise and have trained in fitness aswell...i dont think your heart rate has to increase to lose weight. Personal trainers use heart rate levels to show levels of fitness. So you aim to reach certain heart rate levels as a sign of your fitness level and how you progress according to your own body. Its not about if your heart rate is healthy you dont have to do aerobics for 20 minutes every day - if youre a beginner or just want to get fit you can just do training once or twice a week - its however much you want. a personal trainer will give you a program and then ask you to follow it and record your fitness levels like heart rate and pulse, flexibility, stamina, energy..
