Most of us want a flat set of abs that is defined and looks hot. However many people waste their time by doing exercises that are not effective or if done in a wrong way can be harmful. When you are working out for the lower abs you normally exercise the outer layer of muscles.
Lower ab exercises should be performed correctly as an improper action can incorporate other muscles into the workout. You need concentration, control and focus when you are working for your lower abs. You must not go for any exercise that is beyond your ability or the strength of your abdomen.
When you are exercising for your lower abs you must feel it in that part. If you are feeling that your lower abs is not working while other muscles are exercising more then the workout is being done in a wrong way. In this case you need to stop that exercise and restart it with more concentration and focus. If the muscles in your lower abs are tired then it is tough to feel that they are working.
You need to take rest in this situation. It is a bad thing if you face a pain in your lower back. This indicates that your lower abdomen is not capable of doing the particular exercise or may be you are not doing it in the proper way.
The exercise that you are doing for your lower abdomen should be done slowly and with good control. Your abs will contract at some phase of most of these lower ab exercises. So, it is vital to breathe properly during the exercises. When your muscles are relaxing or stretching you should inhale and when the muscles are tightening or contracting you need to exhale.
