You sound like my doctor that told me I was overweigh at 147lbs and 5'6" tall. I just asked her if she would like to join me on one of my 20 mile training rides in the week- or the 60 miler at the weekend- or one of the sessions of Cardio- Vascuar I do twice a week at the gym. Before making a statement that only unfit people have weak legs and need to train more- Find out more about why people do get out of the saddle when riding.

I will not say that you have to get out of the saddle to climb slopes efficiently- Or tell you to watch the Pro's climb mountains- but for me- Out of the saddle on steep slopes will get me through the steep bits that are not too long- will give a different rhythm after too long in the saddle and give my butt a rest after too long in the saddle.

Attachment is of me a couple of years ago- Only 210 more metres to climb before I get the 13mile descent in.
