I got A LOT of tips about diving from you guys, so I picked the best ones and put them here! (I bolded the ones that appeared most frequently.)

• DO NOT THINK 
• Get your body low to the ground
• Head up and hands out
• Wrap your boobs if you’re really freaked out about them
• Get a comfortable sports bra that has padding
• Practice on a slip and slide
• Don’t jump
• Go down gently but quickly, like an airplane
• Don’t slow down
• Always dive with hands in fists. Open fingers mean broken fingers
• Arch your back to take your boobs off the ground
• Don’t tense up, just relax
• Don’t dive like Super Man, just kinda sprawl out
• Your weight should land on your forearms
• Practice diving by starting on your knees and just laying out. Move up to starting in a catcher’s stance once you get comfortable
