What are some good ab exercises that I can do without hurting my back? Do you have research to support these ideas?
Hello,
The most beneficial way to strengthen your abs, flatten your stomach and not hurt your back is to do abdominal exercises that encourage proper recruitment of the spinal and pelvis stabilizing muscles: the pelvic floor and transversus abdominis muscles. To do this, you need to understand how to “recruit” these muscles (in lieu of using other muscles, which is common) and how to tell if they are staying “on” (instead of using those other muscles) while you complete abdominal exercises.
The transversus abdominis is the deepest layer of abdominals. It does not, by design, create movement. Instead, it creates stability for the spine and flattens the abdominals. It is important to make sure that while exercising the transversus abdominis, it is pulling in and flattening sideways (the fibers run horizontally around the trunk like a corset).
These muscles work best when the pelvis and lumbar spine are placed with the natural curve in the lumbar spine (i.e. when the back is not flattened into the mat) and the back muscles are not gripping.
There are several basic exercises one can practice to find the pelvic floor muscles. Since the pelvic floor muscles attach to the underneath side of the pelvis (these are the same muscles that control urination) they are felt easiest by sitting on a ball and gently bouncing up and down or by folding up a small wash cloth and sitting on it. These devices give some feedback for the individual.
To strengthen these muscles, gently connect these muscles by thinking of lifting them upward slightly. (It should feel like the same muscles that work to keep you from urninating.) It is important to be able to gently lift them for a count of 5, hold them on for a count of 5 and release them for a count of 5. They should not be working at 100% but closer to a 25% level.
Transversus should become active just prior to incorporating other muscles. When the transversus abdominis is recruited properly, you see a flattening or drawing in of the lower abdomen without any noticeable movement of the spine or hips.
To get the look of a flat, strong abdomen, you need a variety of different exercises in your routine. Some include:
1) Challenging the spine in neutral (plank, head and shoulders on the ground) ensuring the spine remains as it starts throughout the exercise
a. Toe taps
b. Dead bug series
c. Scissors with head down
d. One leg circle
e. Push ups
f. Leg pull front
2) Flexion routine- ensure that lower abdominals are set prior to and throughout the motion
a. Roll up
b. Obliques with single leg stretch
3) Extension based exercises- keep abdominals lifting up
a. Swan dive
b. Swimming
More info about the transversus abdominis:
1) acts as a corset, drawing in circumferentially as it protects the spine
2) stabilizer of the lumbar spine by virtue of:
- insertion into the thoraco-lumbar fascia, which inserts into the vertebrae,
- its neurological firing pattern (fires before movement begins so that the spine is protected and prepared
- coordinated work with the other stabilizers including the pelvic floor muscles, diaphragm, deep psoas, and multifidus
3) creates motion around the proper axis of motion, and prevents unwanted shearing or translation of the vertebra which can lead to irritation and degeneration of the discs and facet joints
4) provides compression (in a good way) so that the larger muscles have a stable base to pull from

I was just telling a friend with back pain yesterday that she NEEDS to do Pilates to avoid that in the future and I told her how amazing Melanie, Leslie and Jean have been at helping me with injury recovery. I’ll definitely send her this link — and review the info for myself! Thanks.
