I workout for just 30 minutes everyday because of too many school work and I lift weights, do calf raises, do squats and other else for 3 months and then now I just do it every other day because of more school work in our resume of classes but I just can’t see and feel the improvements, well maybe I felt 3 inches that improved but I mean it has been almost 4 months and just 3 inches, so guys tell me why can’t I jump higher and pls give me some advice and maybe a workout program that will fit my schedule and give me some other workouts to jump higher without weights or with just lite weights.

Thanks for the future answers!

P.S. In case it counts i’m 13 years old and turning 14 this July 26 and my height is 5"7.
I also want to increase my height so can you guys tell me how?
I play basketball everyday at least 1 hour a day and does lifting weights stunt growth because I want to grow to 6’1 or 6"2.
