Several trainers believe in the common saying that no pain, no gain. Whenever someone starts a new fitness routine one may feel a little discomfort. At most it will last for the first few days. This pain is a natural caution sign. There is nothing to worry about but one should pay attention to it. One can start with a good exercise routine. After a few days muscles will get used to the new routine. Lactic acid, micro-tears and other physiological changes happen in the muscles and they become stronger than before. But be alert if experiencing back pain, neck aches, knee joint pain and other symptoms. Then one needs to consult with a specialist. For sure there is some fault in the way of doing the routine. May be the person is working too hard or trying to get quick results, have some medical problem and that exercise is not the right one.

Precautions:
It will take some time to adjust to any new sturdy exercise. So it is better to start slowly. How to set the pace when it comes to exercise depends on so many factors. It varies from person to person, depending on age, experience, and earlier exercise routines and total fitness. The muscles should get warmed up and relaxed before cranking them up. Many of the injuries are caused from the muscles being too cold and not stretching. Sometimes it happens from overextending the capacity. It's necessary to take 15 minutes for warm-up exercises that might include very mild jogging in place or jumping jacks. It helps the cardio and lung systems to effort well. To get joints lubricated and muscles relaxed and gently lengthened slow and gradual stretching during this time. Be sure to take sufficient time to warm up. If the warm up is too short it can easily lead to expand or torn cartilage. It will take a long time to heal this type of damage.

Things to consider:
Pay attention to the posture and avoid leaning on the bars. Look forward, not down at your feet. Relax and maintain the normal stride. Do not take baby steps. Also try to stay centered in the middle of the belt. Avoid wandering sideways or falling too far back on the belt. Set up a routine for exercise.
