Three sets of eight reps on each side, with a minute rest between each set.
• Start on all fours, with legs bent, arms fully extended and back straight. • At the same time, reach right arm out in front of you and extend left leg behind you, so there is a straight line from hand to foot. • Hold for two seconds, using core muscles to avoid twisting your body. • Return to the original position and repeat on the opposite side.
DON’T ARCH OR HUNCH YOUR BACK – YOUR SPINE SHOULD REMAIN ‘NEUTRAL’ THROUGHOUT.
