a arch bridge can hold over 6,000 pounds
It provides you with better neck and back support. It is also much more comfortable. It supports your hip and lower back areas as well. It is great for people who toss and turn at night.
The arch was invented by the Etruscans. The arch then was the only known way of building a roofed structure without using beams. The arch is also capable to support heavy loads and made it easier to build large buildings and bridges. The arch is not needed much nowadays because there are other techniques to sustain heavy weights, such as the suspension bridge and the use of steel frameworks and reinforced concrete for buildings.
not all cats do that, maybe there lower back is hurt. or maybe the cry of joy because you probably don't play with your cat much.
Well herniated discs are quite serious and can get progressively worse if your not careful. I would stay very clear from anything that puts pressure on your back like squats, leg press, and even some things like shoulder press can press down on your lower back. At 15, you really shouldn't be training with weights more than 10Kg anyway, its best to work with your own body weight. I would imagine that exercises like the plank and push ups should strengthen your lower back but avoid sit-ups and crunches which can put unwanted stress on the back. If you don't arch your back, you could probably get away with bench press and chin ups, you could definitely do quadriceps exercises using machines but nothing that causes you to arch the back too much. If you are concerned, you should contact a physiotherapist or your doctor and they will be able to give you much better advice.
Female has much more problems.
