How to make a circle around the player torso?

I'm trying to make a script generate a circle around the Torso. The issue is that I can't get the circle to turn with the Torso, it stays on the Z axis..

wait()
while wait() do
local diameter = 12
local blocks = 24
local blocksize = Vector3.new(0,2,1)
local model = Instance.new("Model", workspace)
for r = 1, blocks do
    local block = Instance.new("Part", model)
    block.FormFactor = "Custom"
    block.Anchored = true
    block.Size = Vector3.new(1,1,1)
    block.CFrame = Workspace.Player.Torso.CFrame + 
        (Workspace.Player.Torso.CFrame * CFrame.Angles(math.rad(r*(360/blocks)),0,0)).lookVector * 
        (.5*diameter)
    wait()
end
wait()
model:Destroy()
end 

Edit: Got it to rotate with the torso, but I can't get it to be around the torso, not be in front of it and behind it. If I change

CFrame.Angles(math.rad(r*(360/blocks)),0,0))

to

CFrame.Angles(0,0,math.rad(r*(360/blocks))))

The parts won't circle around the torso, instead, it only stays in front of the torso.
