#4 – Cable Crunch
This is one for the gym which allows you to work your abdominals against increasing weight as they become stronger. As with the exercise ball crunch, it is a great exercise for the upper abs.
Kneel below a high pulley and grab the rope attachment with both hands. Place both wrists on the top of your head, keep knees bent at 90 degrees and back slightly arched. Keeping back and hips still, pull the rope downward and inwards towards your knees as you breathe out. Stop before you reach the floor and squeeze your abs for a full two seconds before returning to the start position. Build the weight up gradually – there’s no point in sacrificing technique for shifting more weight.
