However, I don't agree with stiffening the arms. I have always been told that the frame is supported from the back, and not the arms, because the back contains much stronger muscles than what connects your arms to you shoulders.
Correct, it is and it does (kind of). This is one of those places where dancing and anatomy don't quite agree with one another. Muscles work by contracting, changing the angle of a joint. As a result, holding the arms horizontal to the ground is inevitably a primary action of the muscles that are above the shoulder joint - deltoid, trapezius, supraspinatus etc. all involved. A muscle underneath the shoulder joint can support and stabilise the ballroom hold position through tone but on its own it cannot place or keep the arm in a 90 degree abducted position. Hold your arm in position, relax as much as humanly possible and then touch your deltoid muscle - you'll see that it's contracting quite strongly.
In terms of my previous post, remember that the stiffening part is an exercise, not the end goal. It creates a step-change in the isometric stamina and tone of your arm and shoulder muscles without building bulk. This has to be done in combination with strengthening of the core musculature (rectus abdominis, internal and external obliques, transversus abdominis, quadratus lumborum, buttocks, gracilis etc) and the back muscles. But the main bit that stops your arms wobbling about in movement is the arms bit. Positioning and supporting with the back is the heart of the final ballroom hold (after you've prepared the body physically) but it's nigh on impossible to have a completely still hold in fast movement and sharp action with completely relaxed arms. On the contrary, the faster you spin and the sharper your actions, the more tone you have to put into your arms in those moments.
