Pea Muscles _ i dont know what it is..please explain

Anonymous. I suppose you are serious so here goes. You have a muscle inside and very low in the abdomen.If girls or boys cut the pea flow midstream this is the muscle used. Need i say more. If you wish to do Latin, Samba in particular, this muscle must be used

this is a reply to the first question by the first anonymous. The important muscle is the transverse abdominus which is a deep muscle which supports the spine and plays a major part in posture. It's nothing to do with the so-called 'pea' muscle which is a pelvic floor muscle and much lower down in the body.
You can feel this transverse abdominus by sitting with good posture in a chair, and then allowing your body to 'slump' .you should be able to feel the muscle relax. You can exercise the muscle as follows: lie on the floor relaxed. Now pull your belly button towards your spine as hard as you can. this is 100%. Now relax again and pull at about 50% and hold it for about a minute. Repeat this about 10 times and ideally do three sessions of this each day. The muscle is meant to work steadily for a long time (so-called 'slow twitch') as opposed to other muscles which can work intensively for short periods (the sort that sprinters use).
When dancing (or indeed standing and walking) the easiest way to 'engage' this muscle is to try to pull your rib cage up and away from your hips. Your body will instinctively use the transvers abdominus to do this.
Incidentally, sit-ups exercise different muscles, which are on the surface and don't really play a part in posture.

Sorry Phil, but you've got the wrong muscle. The muscle you are talking about is important in standing erect, but that is not the challenge in ballroom dancing beyond the very beginner level. Instead, because of the weight position soon developed, the actual phyiscal challenge is to apply the muscle opposing the one you mentioned.

The muscles needed are the surface abdominals, because the task is to keep from bending backwards. And your lower ribcage should be pulled firmly down and not allowed to lift. The curvature of the back that is desirable occurs much higher, in the chest rather than the abdomen.

Anonymouses. Which muscle is used in the body tick as in the Samba
