What is the best workout routine for making abs?
Well, I have heard about crunches a lot. Can you explain how to do them properly?
Absolutely! To do crunches, lie down on your back with your knees bent and your feet flat on the ground. Then place your hands behind your head, or crossed over your chest. Contract your abs and lift your head, shoulders, and upper body off the ground. Hold briefly and then lower yourself back down. Do 3 sets of 10-15 reps. But make sure you don't strain your neck while doing it.
