Do the following three sets consecutively every other day. Rest for 30 seconds in between sets. Start with 10 sit-ups for each set and gradually increase by increments of five up to 30.
Set 1
Do regular crunches. Cross your hands over your chest to prevent pulling on the neck. Make sure your feet stay on the floor and you touch your elbows to your knees.
Set 2
Now do lateral crunches. Put one hand behind your head and touch that elbow to your opposite knee. (example: if your right hand is behind your head, when you come up in your sit-up, touch your right elbow to your left knee) Repeat with other side.
Set 3
Do heels-up crunches, which are the same as regular crunches but this time while keeping your toes on the ground, lift up your heels off the floor during the entire sit-up. At this point, there is a very significant burn in the abs, but resist the urge to rest and finish this set. You can do it!
