if you talk to the older strong dudes in your gym who like to lift heavy they will all tell you to build consistency at a lower weight and only max out on actual meet days.
stick to 4-5 rep range
and yes maxing out on lifts is a surefire way to get injured. do NFL athletes pound their bodies into the dirt all year? no.. they play 16 games 1 week apart and don't hit during the season in practice for a reason
if you go in there like a gorilla and just throw around heavy weight you WILL get injured, not MIGHT, but WILL.
