Can working out interfere with my jump shot?

Yes especially if you work on your vertical if you jump high your body tightens up and your shot=brick the same problem goes for d-rose and westbrook thats why they trash 3 point shooters and if your muscular you have more power in your shot leading to bricks honestly work out and remake your jumper if it's of i prefer curry's jumper a small jump. Arm 90 degrees and high release then it most likely hits the middle of the rim or at least back.
