What is the best exercise to strengthen my abs?
Easiest exercise for abdominal muscles. Lie on your back, knees bent, feet flat. Raise your head up and hold it up. Your abdominal muscles must work to stabilize your rib cage so that you can hold your head up. Hold your head up for 10-15 seconds, lie it back down and repeat several times. Do this morning, noon and night. Gradually reach your hands out over the knees and lift your head and shoulders as high as you can. Don’t worry about a full sit-up. You will get stronger. An easy one you can do standing is stand in front of a counter with your trunk bent forward and rest your hands on the counter. Now in that position try to lift the front of your pelvis with your tummy muscles. Make a little tuck by humping your back a little like a cat stretching. Hold the tuck for a few seconds. This is an isometric exercise you can do intermittently throughout the day. Only one problem with any of these, you will not be able to do them very well until you get your SIJ mobilized to self-bracing.
