Hey guys, im about to start VJB and im 13 years old, im 5"4", 130 pounds, havent done much weight or plyometric training in the past and i cant squat 1.5X my bodyweight. Should i do beginner plyometric and Bodyweight exercises, or no plyometrics at all? Please help me out people im super confused

Also if you need to know

Standing vert- 13 Inches (I know its that bad)
Running vert- 16 Inches (Terrible)

Guys, pls i need serious help, i need to get to at least 20 inches. My Standing and running vert are super bad and pls keep in mind i am active and play tons of basketball but i have not done any serious form of working out like weight lifting and plyometrics. Also cannot squat 1.5X my bodyweight so is it still ok if i do beginner plyometrics or is it going to seriously injure me?
