Abdominals
Introduction
The Midsection
The rectus abdominis, aka the six-pack, flexes the spine, as during crunches.
The obliques assist the abs in this and laterally flex and rotate the spine.
Both the obliques and the rectus abdominis also stabilize the core during exercises such as squats and deadlifts.
Its muscles are 55% fast twitch dominant.
At first you should do low rep anti-extension exercises, like planks, rollouts and reverse crunches, to gain basic strength and stability.
After having built upper basic core strength it is then ideal to move on to weighted exercises to further strengthen and develop the obliques and rectus abdominis.
