Welcome! Time to talk about why I don’t like Sit-ups and crunches and what I do like. I’m obviously right because I am awesome-DONT argue! So please listen because I want to save you from making the same mistakes I made as an athlete and coach. My aim is to  provide you with some suitable replacements that steer you in the right direction when it comes to trunk training.

Often I have athletes and clients who ask me why their program have no crunches or sit ups. They have been doing crunches for years and now Nate won’t let them do it.

Why wont Nate let me do it!!! 

First off that is partly the problem, they have been doing flexion based exercises as trunk training for years and this has led to dysfunction and all sorts of issues with the t-spine and lumbar , not to mention our poor hip flexors.

As most of us have done  sit ups and crunches for years. As Lorna Botwright has noted: it has actually led to excessive utilization and tightening of the hip flexors. This is not good.Instead of focusing on controlling the breathing and movement, while co contracting the trunk musculature (glutes, lumbar and abs), bracing the abs and using them to pull the upper body forward.

The problem with the majority of people is they see the “core” or trunk as abs. However the trunk is actually made up of the quads, glutes, abdomen, back muscle groups, deltoids and pectorals. By focusing just on the abs we miss the boat when it comes to developing a powerful trunk.

My problem with the push up derives from the face that the majority of clients utilize the hip flexors to pull or in many cases jerk the body into the top position of the sit-up.

This is issue exacerbated by a high number of people being stuck in an anterior pelvic tilt, mostly caused by excessively tight hip flexors and poor external rotator strength, yup dem glutes and weak trunk.

They repetitively load the lumbar spine through flexion and extension. Thus increasing mobility through this region and this is really not what we want. We really we want the lumbar to be stable.

Tight hip flexors, weak glutes and poor trunk strength often lead to loads of problems like hamstring injuries, lower back injuries and often excessive t-spine flexion. If you are finding this article interesting then checkout how trunk training can fix lumbar spine pain

Front Plank

I would suggest focusing on isometric/quasi isometric exercises. Resist that extension, flexion and rotation. Also work on that neutral spine position, feel it,  work on maintaining it and think about how you would hold these positions during your training and sport.

This type of training is often seen as a form of functional training. If you want some amazing functional trunk strength then you should learn more about these principles, ideas and exercises by checking out Michael Boyles work and Tony Gentilcores website.  You will instantly be cool and have sexy abs (okay maybe not but they are awesome). You may even look as good as me. Pushed if too far? Thought so.

So when can I do a Sit Up?

Only once the prescribed exercises are done to a satisfactory level will I ever allow the athlete or client to progress to exercises like the adjusted Janda sit-up (which has some flexion). It should only be used as part of your trunk training regime once a high level of trunk control and stability is obtained.

I like the Janda sit-up because of a process called reciprocal inhibition (as one muscle antagonist contracts the other switches off) that forces the hip flexor to be used less due to the forced contraction of the glutes and hamstring musculature (or something like that.)

I will say that it is a damn hard exercise to do and requires great stabilization of the trunk. Therefore this exercise only requires a low rep scheme starting with 3*5 reps and working to 5*5 reps.

If you would like to know more about the Janda sit-up, or safe progressions into flexion based trunk exercises then I would highly recommend reading Hardstyle Abs by Pavel Tatsouline. The guy is awesome and is seriously strong!

However if you have lower back pain I would say avoid these exercises. Stay away from flexion based exercises.

Janda Sit-Up

Where athletes go wrong is they go for longer time, more sets or more reps, instead of focusing on spinal alignments and muscular co contraction. Work on creating greater tension rather than just adding reps and sets. For more information on trunk training.

Here are some exercises I would recommend you put in to your trunk training session:
