What should my heart rate be (beats per minute) during exercise?
I’m female, 22 and weigh 65kg. I’m trying to improve my fitness levels at the gym and wondered what my heart rate should be when I’m working on the cardio vascular machines?
Cardio = 220 minus your current age x 90%
Fat burning = 220 minus your current age x 70%
So, for example, if you are 22 and you wish to train your heart, 220 – 22 = 198 x 90% = 178 bpm. You need to work up to this zone and stay in it for at least 15 minutes to get benefits – 30 minutes would be better.
