OK, I know this is a rather silly question but I still have to ask it anyway. I'm mid 40's and use cycling for fitness. I have a decent road bike (Specialized Allez Expert Double) and really enjoy it. After 40 years of just mashing on the peddles I put clips on the bike and got shoes.

My question is how do I train myself to use them correctly and just what is correctly. Instead of mashing on them I should also be pulling with the off foot. Problem is it is difficult to concentrate on doing that and my knees end up really fatigued at the same time. What am I doing wrong and exactly how am I supposed to peddle with clips.

Go ahead and laugh (I would) but give me some advice also.

Thanks
