Improving Fitness and Sport training tips
To begin with, fitness is very important in any sport and in volleyball the focus is on the lower body entirely or majorly because the game requires higher jump.
Since volleyball is a sport where your lower body needs more training, some exercises like jumps with different weights, jumps on one leg, agility and running can help improve the lower body strenght. Next for the core you can do push ups, plank, crunches, and also other core exercises with different variations. For the upperbody practice with body weight, triceps and biceps and then some variations for the shoulders. Cardio is also very important so please make sure that one training session is dedicated to it.
