6. Crunches
Primarily an abdominal exercise.
How to do: Start on an exercise mat on the back with the knees bent and arms across the chest. Do Not interlace the fingers behind the head or neck as this may cause injury as you pull forward.
Using the abs and core, lift the upper body off the mat and touch the elbows to the knees and hold briefly and then return to the start. Perform 2 or 3 sets of 10-15 repetitions. As a crunch variation, add a slight turn or twist as you lift up and touch the right elbow to the left knee and alternate.
