Anyone who knows me, knows that I am a big fan of practising the stomach vacuum as part of my abs training. This is not just for vanity reasons, in that it helps keep your midsection tight and prevents any stomach distention (plus it looks cool!). But also for the overall health benefits of training the Transverse Abdominis for a strong core and healthy lower back.
Normally I like to include stomach vacuums as part of my abs training. I mix vacuums in with each abs exercise I do, in that I hold a vacuum for a second or so after each rep. I try and do this daily if I have time.
These are some of the exercises I do.
