Do squared edged 20KG olympic plates alter deadlift range of motion ?

[tsmithy]

I am considering buying an olympic bar and weights and have a few basic questions.

1) Would buying a set with squared off edges alter the range of motion in deadlifts? For example the 20KG disks have squared edges and may have different diameter to the usual round 20KG olympic disks?

2) Are plastic coated weights less durable then metal?

Thanks in advance.

Why on earth would you want square weights? Especially if your doing olympic lifts. Think out it. When you come down on your dead, and you hit the edge of the weight with the floor, that could come back and smoke you in the shin.

We have 20kg olympic rubber weights at my gym and I love them. I don't know how old they are, but there holding up fine

The weights are 12 sided, has anyone deadlifted with these and had any issues?

A square has four sides.
A dodecagon has twelve sides.

Answer: No.

anything that isn't round is a pain in the ass for deadlifting

I agree. Round plates are the only way to go.

I think they should just bring back the giant iron spheres of old.

Yes. If you have a choice, get round plates. Having plates w. edges will not alter the range of motion, but when you set the weight on the ground, the bar will shift. Not a problem if you never ever plan on deadlifting anything other than singles, but it is a real issue if you do reps.

Thanks heaps guys thats answered the question perfectly....round it has to be, shame there are not any round ones on e-bay here in Australia.

Ohh and thanks betastas for letting me know the name is dodecagon, i doubt the people selling them even know that!

Obscure trivia is awesome.
