Now that you have practiced the upper longissimus let’s get you working on the lower part. Again just like all the ab muscles the back muscles have a lot of different ways it could be worked. Use this lower longissimus to connect to the upper you have been doing.
Parameters strengthening:
- Do 3 X up to 100 reps
- Make sure you tuck your pelvis so as not to arc your back and compress your spine
- Think of pulling your thighs off the ground with your knees locked so to not just use your hamstrings.
