Lying leg raise
 

Flat bench lying leg raise

Lie back on the bench with your legs extended in front of you off the end. Use your hands to grip the bench and steady yourself. Keeping your legs straight as possible, exhale and raise them until they are perpendicular to the floor. Slowly lower to the starting position.

Top tip: Force your lower back into the bench by tensing your core. Not only will this ensure you use more of your mid-section throughout the rep, it’ll take strain off your spine and help injury proof the move.
