Making Back Strong
1. Lying on the floor with bent knees.
For doing this exercise you need to be lying on the floor in such a position that your back is on the floor and it must be firmly pressed against the floor. Then bent your knees. Now after that start raising your left leg and bring it to your chest but at the same time you need to tighten your abdominal muscles. When you have brought your left leg to your chest hold it there for 10-12 seconds then reverse it, after that do the same procedure with the right leg.
2. Stomach Against Floor Exercise
You must have seen this exercise during yoga time on T.V, this one is the most favourite of mine, for this you need to lie on floor with your stomach touching against the floor. Make your arms straight out, like if you are diving in pool, same goes for legs, these should also straight out behind you. Now you have to make your self in "U" shape by raising your arms and legs at the same time. When you have fully stretched making your self in "U" shape. Hold there for 10-12-15 seconds ( which ever counter you like ), then come back to normal position, repeat the procedure again. This exercise should be done for at least 10-12 times, I do it when I go to office and before sleep time, gives me lots of relief. Try it you won't regret it.
I hope you will enjoy doing these exercises which I do :)
