Correcting hitting mechanics

For the stride problem, take your stance, and set up 2 bats beside your front foot, pointing toward the pitcher. One bat one one side of your foot, and one on the other side. Practice taking your strides, you should stride between the two bats without stepping on the bats.

The lower body is extremely important in the swing. You need to use the legs to help rotate the hips, which in turn rotate the shoulders giving you some bat speed. You can take a bat, and hold the bat behind your lower back, holding it between your elbows. Take your stride and practice hip rotation, using the bat to help drive the rotation. Focus on straightening the front knee, going from a flexed front knee to a firm straight front leg. This is what drives the front hip cuasing it to rotate.

A better description for correcting my lower body errors is that my hips do not follow through easily, it almost seems as if it is a forced motion. Same question, any other ways besides doing more reps that can help?
