If you are trying to learn how to jump higher you have to take into account both the strength training aspect and the speed at which your muscles can contract. A good plyometric workout routine will incorporate both of these types of exercises.
The most common exercise you will come across is the squat. This is a great way to build up strength and muscle in your legs and glutes. Will squats make you jump higher if done alone? Yes they actually will but you will see better results if you also do some plyometric exercises. Don’t be fooled with gimmicks like strength training shoes that are supposed to increase your vertical leap. These vertical jump shoes do not actually increase your vertical leap. All they do is strengthen your calves a little bit but I highly advise against them because you shouldn’t be in that position for long periods of time, it will throw off your walking gait.
So where do you get the best vertical jump training? There are a few programs online that you can buy and to be honest the majority of them are not worth the money. This does not mean that they are all scams! I do recommend the Jump Mentor and the Jump Manual. They are the 2 best programs in the market.
