Is it bad to do crunchs 3 times a day everyday?

Answer 1

It depends on how many you're doing. If you're doing 3 sets of 3 crunches 3 times a day, I would say no unless you have some kind of strange medical condition. If you're doing 3 sets of 3,000 crunches 3 times a day every day...you'll injure yourself.

Just pay attention to your body and how sore you are. Your abs are just like any other muscle in your body...if you work them too hard you will harm them. If you are just starting out, I would recommend that you work your way up to doing 3 sets of 25 crunches 3 times a day, 3 days a week. When you can do that comfortably, start doing 4 sets of 25 crunches 3 times a day, 3 days a week.
