In order to improve your vertical leap you should focus most of your attention on increasing the strength of your quads, hamstrings and calves. Why these muscle groups? Because they are responsible for more than 80 percent of your jumping power.
The following exercises will help strengthen these muscle groups and increase your vertical leap at the same time. Let’s take a look at some of my favorites:
Heavy Squats – This is BY FAR the best overall exercise you can do for your vertical jump. It hits every muscle group that we are focusing on. Notice I said “Heavy” squats. When performing this exercise you should not be able to do more than 8 reps per set.
Paused Jump Squat – This is a good variation to the regular squat. Use a weight that is about 20% of your max. Squat down so that your thighs are parallel to the ground and then hold this position for 3 seconds. Next, EXPLODE UP and jump as high as you can. Do 3 sets of 8.
Sprinting – Sprints are an easy way to improve your explosive power, top speed and vertical leap. A few times per week you should perform 3-5 sets of 50 or 100 yard sprints.
Most people do not focus on their form when they are jumping, and this is usually an area that could use improvement. You can instantly receive 3-4 inch gains just by practicing the proper jumping techniques. This was an area in which I had trouble and once I made a few adjustments to my form I got an immediate 2.5 inch increase! So that was time well spent
