Core strength: Arm and leg crunches

Core strength arm and leg crunches build strength in the six-pack muscles, giving you that sculpted look you may have thought exclusive to celebs with expensive trainers – not anymore. Not only does this move promise an aesthetically pleasing look, it also comprehensively targets the stomach muscles that will give you fluid, free running.

Technique

• Lie on your back on the floor.
• Extend your left arm and leg.
• Place your right hand behind your head and keep your right leg at a right angle.
• Crunch your head and arm up while lifting your leg.
• Touch your left leg with your left arm.
• Return to the start.
• Complete one set before changing over to the other side.

Be safe

Don’t let your lower back arch off the floor
