#5 – Hanging Leg Lift
Although traditionally done holding onto a pull-up bar in the gym, with a little imagination, this can be done almost anywhere – there are plenty of trees! Although more intense than the reverse crunch, it too targets the lower abdominal region.
Grab a bar and just hang until you no longer swing, maintaining a slight bend in your knees. Slowly raise your legs upward, keeping them straight whilst breathing out and rolling your hips upwards. Your legs should be roughly parallel to the ground in the end position. Ensure that you perform it slowly, without using momentum – try 5 seconds up and 5 seconds down.
