Hey does aynbody know all the muscles that waist twist with a stick behind your neck works? Also, do pullups help develop your serratus muscles? thanks
The intercostals are used for movement of the ribs such as breathing. To hit these muscles you need to twist coupled with a crunch movement so do the following:-
- Twisted Knee raises (Knees to elbows)
- Side Leg Raises (Dont lying down)
- Forward Leg Kicks (Done lying down)
- Bent Side Leg raises
The angle of twists with the bar does not work the inters. It may stretch the muscles but not work them hard enough
