Hello!
So, when I had my baby a year and a half ago, I was about a stone and a half heavier than my normal weight. Very gradually, I lost it and now have a BMI of 19.7. (I'm 5"7 and weigh 9 stone).
I don't drive and live in a big city, and so I walk most places. I usually get about 10,000 steps in a day. But I don't do any kind of weight bearing or cardio exercise. As I'm a SAHM, I struggle to find the time. Of course, if I really was motivated I could go for a run at night when my husband has finished work, but it's the last thing I feel like doing at that time of day.
Is it very unhealthy that I basically never get my heart rate going? Are the risks of being slim but unfit similar to those of being overweight?
