I was deadlifting today. I am trying to improve my strength so I tried to deadlift my 3 rep max. At the last rep, my grip was failing so I dropped the weight at the top of the motion with a loud clank. A guy seemed pissed off and told me that I need to use some cushioning to soften the noise. He also told me that what I am doing is very dangerous and I should wear a lifting belt. Some random guy told me that I should be deadlifting in the squat rack and shouldn't lift that heavy. I admit that banging weights is annoying and I promise to use some cushioning but I am skeptical about the lifting belt. I am one of the younger (and smaller) guy in the gym so I just nodded in embarrassment afraid to disrespect the older guys.
My question is:
1.) Should i use a lifting belt for deadlifts? I have lifted for more than 1 year and never had any injuries from weightlifting.
2.) Should I continue using heavy loads (like 5 rep max and heavier)? I want to be stronger but I always thought that I should push my strength to the limit to improve
3.)Should I continue deadlifting? In my gym, very few people deadlift and it seems that deadlift gets a very bad reputation in my gym.
P.S: I am 19 yrs old and i weigh 63 kgs (138 lbs). My deadlift 3 rep max was 110 kgs (242 lbs) if that helps
