What stage are you at with regular weight / strength training? E.g. How much weight are you squatting / deadlifting / leg pressing? How old are you? What do you weigh?
Right, the stage you're at is an important consideration. For instance, I myself find it valuable to jump rope with my training partner, Sammo Hung, sitting on my shoulders. Somebody at a lower level of fitness might be better served by one of the jumping programs marketed to basketball coaches, though.
My kicks, are powerful right now. I have good technique, and good power. I weigh 130. I havn't reallydone any squats, but deadlifts, I did 105 easly, I havn't really done any of those either.
In that case you need a good basic strength training program using heavy compound lifts - I'd recommend the following done twice per week.... 1. Squats - 3 x 15reps 2. Alternate between Bent leg deadlifts (3 x 10) & leg press (3 x 15) 3. Flat bench press - 3 x 8 4. Chins - 3 x max 5. Seated shoulder press - 3 x 8 Until you can squat with twice your bodyweight, in good form - forget plyometrics.
(And that goal was set, I believe, because at lower strength and experience levels, doing unsupervised, unguided plyometrics is an easy way to strain muscles and snap tendons)
