belts in my opinion are needed for any heavy movements which will put stress on your back... they prevent side to side movement of that area which will really hurt your back spine...

if your doing the movement in perfect form then your back should be fine without a belt...

but why take a risk... what if for some reason your grip jerks or someone accidentally walks into the bar whilst your lifting???

i suppose the same thing can be said of wearing a helmet on a bike... you may be perfectly safe at 200mph on your hyabusa... thats not to say mr magoo in his micra isnt going to come along and knock you off it!
