Warm up, then move into your hardest gear. Start with your left leg only and do about 20 rotations, then clip back in with both feet for another 20 rotations, then move to the right leg. Once you have gone through a set in your hardest gear, move to the easiest gear. One leg will generally be easier and more fluid than the other. This morning I did several sets and by the end I had gotten rid of the hiccup at the top of my stroke on the left leg. It's a perfect workout for the trainer.
