yea dont worry il find a way to jump outdoors and indoors. I know its still early days and im not in any rush but i just wanted to know whether jumping 2-3 times a week will be enough in the long run or will i have to add other techniques at some point?
depends, running jumps at max effort and high volume can be a VERY intense stimulus, but the way a lot of people tend to do them isnt. Adding explosives to your weight training schedule is always good if you know how to perform them properly and give a measurable way to track speed strength increases in the weight room.
Jumping exercises/drills and true plyometrics have their place but also need to be used correctly. Most jump drills and exercises are less intensive than all out running jumps, in many cases the best use for them is BEFORE all out jumps in the training plan. True plyometrics are often more intensive than running jumps at max height, but not the same skill or movement pattern, so that has to be factored in, and they tend to be more effective once youve peaked or plateaued in your training with all out jumps of the nature you want to improve.
A good way to add in a progression of high intensity jumping exercises and plyos is to
1. movement efficiency work/ low intensity jump drills
2. landings off low boxes, svj, rvj, bounding (low intensity)
3. landings from higher boxes, depth jumps, higher intensity bounding, max effort running jumps
the higher intensity the exercise, the lower the volume and vice versa. Skipping ahead to the latter stuff will make it much more dangerous and much less effective.
