Instructions
Lay down on an exercise mat with your feet flat on the floor and your knees pointing upwards bent at a 90 degree angle.
Lift one knee towards your chest and, holding the resistance band in both hands, loop the centre around the base of your foot.
Contract your glutes and extend your leg outwards at 45 degree angle until your knee is almost straight.
Hold this extended position for 1 second before allowing your leg to be pulled back into its starting position.
