Jumping on a trampoline can help you jump higher because it provides the additional push that you need. It also motivates you to keep trying and it’s a lot of fun to do. If you have a lawn, get a trampoline or get a membership in a trampoline park.
In order to jump higher, you have to make sure that your leg muscles are strong and healthy. Without good muscle force behind your jump, you won't get very high. During your workouts, make sure to focus on your leg muscles as well as flexibility and strength in your joints. Keeping your knees and legs healthy will help you get your jumps higher at a faster rate. Healthy legs will get you far!
To jump higher, you need to train your legs. To do an explosive jump, your body needs the right training. Performing burpees requires you to jump, squat, and do a push-up which requires you to use almost every muscle of your body. Training to jump higher when doing burpees can help you build capacity so you can utilize the energy in your body to jump.
A squat accompanied by a jump uses your body to push harder and engage your core. To take the squat jump to another level, carry dumbbells in both hands. You can start with regular jumps squats and when you are ready to get to the next level, start with 0.5 or 1 kg dumbbells.
