You do look great, really slim, how tall are you? I can see what people mean from your other thread about whether you need to lose anymore.
Also altho BMI is only a guide anyway, it is least helpful as a guide for those who are very active, with a high amount of muscle. With your riding you are active and are probably muscular (in a nice way) which means it is all the more reason to be cautious about going off your BMI x
