Today I worked with some bigger stuff, 1 1/4″X5/16X36″ flat 
steel and 3/8 X 3/8 X 36 inch cube stock. This is one of my better coils on the flat stock, it is very stiff so it bends well once you can get it to move. The bar weighed in at almost 9lbs for a 36″ piece so its a pretty good bar to work with. The cube stock gave me all kinds of problems. I wanted to twist it out and wrap it but i could not get a good coil, so i stopped that and just bent the crap out of it for 20 minutes, great upper body work out. 
After that i did 6 minutes of swings 32kg/115 reps. I didn’t want to do swings today, so i only did a little bit.
Finished with David Hornes grip work out. 2 hands plate pinch holds, barbell roll ups (works your cursh grip), BB wrist curls and reverse wrist curls. After scrolling the bars my wrists were fried.

hey adam,
do you know if that skinnier thick steel harder to bend than thinner round pieces?

I am not an expert yet, but i know these things which i hope will answer your question.
Steel strength is based on several factors:
1) The way it was made and what other metals were in the “batch” of molten metal when it was poured.
2) The exact method used to make the object-forged, smithed, cast, was it cold rolled, hot rolled, how many times was it hardened ect.
3) The shape and diameter. 3/16 diamter round stock compared to 3/16 square stock for example: both come to the same thickness in the middle, but the cube has more volume because it is a box shape.
For this exact bend i did last night, I had a goal in mind for the flat stock, and it came together. The cube stock was different. I had no plan other then to bend it and play around. but the 3/8 cube was a bitch to get in to position once i started twisting it.
