I'm very new to exercise. I havent exercised regularly since I became pregnant two years ago. I had started doign some social dancing for about 30 minutes a day last week and now I'm going to the gym to use the treadmill for my main exercise.
My question is how do I know I'm working enough? What should I be feeling?
I find myself stopping my exercise at around 30 minutes. I'm never get breathing heavy but I do breath a bit more then resting obviously. If the heart rate monitor on the machine is accurate I never go over 145 and usually stick to 130ish beats per minute. I spend 5 minutes warm up and 5 minutes cool down and 20 minutes at the target heart rate.
I usually think to myself I don't want to walk to much because I don't want sore feet or ankles at the end of the day. I really need new shoes but I have to wait for payday. I think my tennys are too old and don't have enough support.
