This happens at around 20 or so crunches, which isn't a great workout. What are some well-mannered alternatives that don't put so much pressure on your lower back?What ab workouts can someone do near a discouraging stern?
I'm not sure how my "rear legs pain" is anywhere equivalent to what you are experiencing but I do have a problem doing standard crunches and situps because it hurts my wager on and neck. I took proposal from a friend and bought a stability ball, it make it tons easier while still giving you the workout you want.

Try this isometric exercise to start. Just pull your stomach contained by. Try and touch your belly button to your spine, and hold it for a 20 count. This is effective for immediately. You can do this as many times a hours of daylight as you like, even while driving. Hold the contraction as long as you can and try to breath typically. But no ab exercise will help you lose mass...reasonable diet and exercise can lone do that..
