Hello
Does anyone have any experience with measuring forearm circumference? I'm struggling to get repeatable results so it's difficult to know exactly how much stronger I'm getting from training.
Cheers!

My fore arms are definitely bigger than malcolm's, does that make me stronger than him :bounce: :-\

I think you need an SEM.

Tape measurements of muscle circumference have moderately good repeatability. They can be improved a little by applying a consistent tension to the tape (widgets available (http://www.balancedcanineproducts.com/product/gulick-ii-tape-measure/)), referencing measurement point to a bone landmark (e.g. circumference 7cm distal to the medial epicondyle (http://diseasenames.com/wp-content/uploads/2017/09/palpation-of-the-medial-epicondyle.jpg)), and taking a mean of three measures.
Ideal measuring tool would be imaging ultrasound. I can't see the point to be honest though.

Intuition tells me that forearm circumference wouldn't be a particularly effective way of measuring gains in strength compared to more direct measurements like hanging off the same edge for longer or with more weight added.

I once saw a video of Lee Priest measuring his biceps and forearms with a gizmo with a rounded edge to be placed exactly on the muscle. He was also talking about a much sought after ratio of 1:2 between wrist and forearm circumferences.

I approve of this extremely geeky joke.

If someone who's friends with me on FB can let me send a pic over, I have a description and photos of a method for you.

My recommendation is to glue several £20 notes together end-to-end, wrap the assembly around your forearm, and mark where it overlaps. Then post the money to me and I will email you back a precision forearm circumferance measurement, along with a motivational message to keep on training.

what circumference counts as an 8A tick?

It's scaled to your weight, but, fear not, my method takes the issue into account. If you weigh less than 65Kg, send me glued together £50 notes, rather than £20s.

Yep, Superb Mike!

Thank you for the advice everyone. I like the idea of measuring relative to the medial epicondyle. I've decided to measure 8cm distal. I'm currently 1.8 relative to my wrist. Another inch needed to meet the golden ratio of 1:2 then 8C has to be on the cards!

He was also talking about a much sought after ratio of 1:2 between wrist and forearm circumferences.
Can I claim 8A then?

Have you sent moose the money?
