In fitness, some people are confused about the topic of upper abs exercises and lower abs exercises, so here is some information to set the record straight. The main muscle, that people talk about when they discuss the upper abs and lower abs, is the rectus abdominus. Rectus means straight, and abdominus means the abdomen which put together gives the idea, rectus abdominus runs straight down the abdomen. This is the muscle which gives even the lean person the six pack look.
The rectus abdominus is 1 muscle, but it has tendinous intersections that separate muscle fibers forming distinct sections. As most people argue rectus abdominus cant be isolated and trained when the entire muscle is idle and put o training. But conversely we can emphasize one area over another even while the entire muscle is not put to use.So the problem comes with people using the terms isolate and emphasize interchangeably.
Our nervous system is so intricate. Each nerve has thousands of nerve cells and each muscle has thousands of muscle fibers. This allows us to move with accuracy, precision, agility, and grace. The rectus abdominus has multiple nerve endings which are coordinated fashion to create a variety of movements. The nerve endings coordinate our body movements and the upper and lower abs are emphasized upon when we do various movements. The upper abs, which is the upper part of rectus abdominus is emphasized when we move the trunk forward like in a crunch or sit up. ball crunches are also a good upper abdominal exercises. The crunch machines and ab training muscles are good upper abdomen tightening exercises.Apart from upper abs the lower abs are also emphasized while doing crunches. The entire rectus abdominus muscle is trained in any good abdominal exercise when your trunk bends forward or flexed.
The lower part of the rectus abdominus are finely emphasized when you do revrse crunch. In reverse crunch the pelvis moves towards the trunk. Leg raises and flutter kicks also work out the lower abs.Again, the upper abs work during reverse crunches and leg raises. There is just more emphasis on the lower abs when the legs are moving.
However I must warn you that these abdomen exercises are definitely not a magic cure. Doing these upper and lower abdomen exercises alone will not melt that fat deposited for ages in your rectus abdominus area.... This is known as sot reduction myth. If you really want to get rid of those irritating fat contet of your body adopt a comprehensive approach including diet control.
In regards to your ab workout, try to exercise your abdominal muscles 2-3 times a week, and include both upper ab and lower abs exercises to work your body from a variety of directions. By using different forms of exercises, you will have a more balanced body.
