Lower ab exercises 30 day challenge

The 4 exercises in this challenge target the lower part of the “6 pack” muscles. Abdominal curl type exercises that involve lifting the upper body off the floor are good for working the upper and middle part of this muscle group, but they’re not so good at hitting the lower part. The best lower ab exercises involve the legs being lifted rather than the upper body.

What the abdominal muscles do

There are 4 layers of abdominal muscles. The deepest layer is mainly involved in core stability and is what you need to train for flat abs. Read this post to learn more about core stability.  The oblique muscles form the middle two layers and their main movements are bending to the side and rotating the upper body. See this post for an obliques workout. The top layer is the “6 pack” set of muscles (proper name rectus abdominis). These muscles carry out the action of flexing the spine. Depending on what part of the spine you’re flexing, you’ll be working different fibres of the “6 pack”. Lifting the legs towards the body, as in the exercises in this workout, mainly works the lower fibres.
