Heavy exercise! You are really working the abs here and hitting the Pilates sweetspot: the transverse abdimonal muscle(s). When you straighthen your legs as much as possible, you will feel a burn in the waist, this is what you need. Just above the plevis on both sides!
2. Stable leg stretch
This is the stable litle brother of the single leg stretch. It works on pelvic stability. You have to make sure you don’t bring back your knee to much. That’s the whole point of this exercise. Its’s also nice to work with a neutral spine and to lay the head on the mat while working the abs.
3. Lower leg cross
This might not seem much at first, but as you try to hold still both the upper legs and the pelvis, you will feel it! Nice pelvic stability exercise which also very much focusses on ab/hip muscle activity. Don’t shake your knees too much, that might hurt them.
Great exercise for all of the abs. We are trying to aim for a upper body turn-movement here with a stable pelvis. The twist works the lower ab, obliques, tranverse abs while the reaching works the main abs (sixpack-area). Lovely exercise for a total ab workout!
5. Crossing legs
The crossing legs is advanced territory for Pilates ab exercises. t’s hard to just move the arms and legs while you hold still the upper body and head. If you are able to do it, everything will fire! The ab abs are working, the pelvis and hips are working and the legs start burning as well.
6. Inverted hundred
The inverted hundred is also advanced territory. You have to know how to stabilize your head from the abs/upper body. If you use the neck muscles, then this is a horrible excercise. The challenge is to use the abs, then it’s quite fun!
Alright, that’s it for this 6 ab exercises. Great job!
