Question: What accessories/supplements work to augment/replace techniques

Is there any pumps, commercial products, etc that work to replace certain techniques? I saw there is a review forum, but I’m not asking about any specific product, just in general which exercises can be replaced/augmented well by which products, if any?

I’m just asking a GENERAL question .. Not for any specific product. I don’t see anything listed on this site that says “here is what is good for replacing stretches: ., Here is what is good for replacing this: .” That’s all I’m asking.

Thats because you’ve answered your own question.

If there was a better replacement for exercises, we’d all be doing that instead, wouldn’t we?
