Some people can naturally jump well, while others are more challenged, but both groups can improve from good jump training. This is another topic that is discussed in my book and DVD, Train For Your Sport. Here are the basic conceptsto get you started on the path to awesome jumps:
Jumping requires power.
You must train your muscles to contract quickly in order to get real height. This comes from practicing jumps a few times each week. I recommend to do them early in your workout while your muscles are fresh. To keep things simple, you might start out with 2 sets of 10 jumps progressing over weeks to 4 sets of 10 jumps. Do a variety of jumps to get good at all the ones you need.
More strength leads to more power
Jumping is not enough. You need to be doing some strength training to make your muscles and connective tissue stronger. The stronger they are, the more power they can generate and decrease your chances of injury. Be involved in a strength training program 2-3 times per week. Details can be also be found in my book and DVD, Train For Your Sport. I recommend strength training follow the jump training in the workout regimen.
Increase the intensity as you get better
Once you have gotten stronger and your jumping has improved, you may have to start jumping onto and off of small
heights:12-24 inches to increase the load in order to improve more.
