Based on the provided reference, a "Matrix Machine" appears to refer to exercise equipment used for physical training. The advice suggests its use for exercises targeting the back and shoulders. Here's how to use it, based on the video excerpt:
-
Foot Placement: Place your light-side foot forward.
-
Body Movement: As your light-side foot moves forward, pull your heavy-side foot back.
-
Target Muscles: This action primarily works the muscles in your back and shoulders. The video specifically mentions not using your biceps.
In summary, the matrix machine described involves a forward-backward leg movement designed to engage back and shoulder muscles during exercise. It's crucial to consult a professional trainer for proper form and guidance to avoid injuries when using any exercise equipment.
