Using jump higher workouts to gain a few more inches on your vertical is a great advantage to your game in Basketball, Volleyball, Football and Soccer.
In Basketball it can be the difference between being able to dunk or not.
To dunk or not to dunk? That is the question.
In Volleyball, not having the extra inch is the difference between lethal spikes or not.
Being able to jump better and higher will certainly increase your performance in a lot of games but how can you achieve it? More to the point, what are some good jump higher workouts? Is overall conditioning important? Yes.
Make sure you are at a good fitness level before even attempting to increase your vertical.
Using a jump rope is great for rapid conditioning.
Works legs, abs, Cardio and even forearms.
Make a habit of it, you could even do this whilst watching TV! What are the best leg targeting workouts? There are many leg workouts but you have to target the muscle groups and fibres used for jumping.
Only doing squats with heavy weights wont cut it alone.
Aim for the following:

• Deep Knee Bends.
  Start standing.
  Slowly bend at the knees while keeping your back straight.
  Crouch down as low as possible and slowly rise back up.
  Do this 15 times.
  Over time increase to 20, 30, etc.
  
• Deep Knee Bend Jumps.
  Start standing.
  Crouch down as described above but do it more rapidly, almost touching your bottom to the ground, then explode upwards as high as you can and as fast as you can.
  The moment you land, immediately crouch right down and launch back up again.
  Do this 15 times, and when you can, increase to 20, 30 etc.
  Think about explosive power and make sure you are heading straight up, vertically.
  try not to launch forward or back.
  
• Toe Raises/Calf Raises.
  Stand on a step or a stair with just your toes touching the step.
  Raise yourself up as far as you can and then lower yourself all the way down, so your heels drop lower than your toes.
  Do not bend your legs.
  Do not bounce in this exercise, it may cause injury.
  

Can you advance on these Jump Higher Workouts Yes.
Simply add weights.
Start off light.
Even adding 2 tin cans in each hand will help but dumb-bells are best.
DO NOT add weights to the Deep Knee Bend Jumps until you are fit, strong and confident.
Even then be careful and start lightly! Try to workout 4-5 times per week.
Don't train everyday, the intensity often causes people to quit after a couple of weeks.
You want to be training for months and years and constantly improving not just blasting it for 2 weeks, getting bored and quitting.
Add jump higher workouts to your routine and watch those extra inches come into your vertical jump.
