If you’re looking to improve your basketball skills and want to jump higher or even dunk, vertical jump programs can help you out. Which jump programs actually deliver the goods though? There are so many different ones out there, and most of them make claims that they can’t back up. If gaining 15 inches to your vertical without was really as easy as some programs make you think, wouldn’t everybody be dunking by now? So how can you find a really good vertical program?

Here are the 5 things you should look for in a vertical jump program.

1. Uncomplicated instructions
It’s important that you can understand what the creator of the program is talking about. It shouldn’t matter if you’re a beginner or a professional, the program should be easy for anybody to start doing without a glossary of complicated terms and words.

2. Plyometrics and weighlifting workout routines
Only programs that have plyo and weight workouts are helpful. If the product you’re looking at doesn’t have these things, there’s no way it can help you jump higher. Plyometrics is all about explosive movements, which is something you’ll need when you try and dunk.

3. Customizable workouts
All athletes are at different stages, and what might work for you probably wouldn’t work for someone else. This is why it’s very important that a program has enough workouts for beginners, intermediate and advanced ballers. That way, if you’re really good at plyometrics workouts, but you’ve never lifted weights in your life, you can create a special workout made up of the exact programs that you need.

4. Improves overall strength and speed
If you can jump higher, you should automatically be stronger and faster, so if you’re only able to jump an inch or two higher, the workout system you have is probably not helping you get stronger or faster.

5. Be Affordable
You shouldn’t have to spend an arm and a leg just to jump high! There are some workouts out there that are worth the money, but very few of them actually are.

If you can find all five of these things in a vertical jump program, it’s a good one, and you should try it out.
