TAKE IT UP A NOTCH

Feel like you can lunge in your sleep? Crank up the difficulty with these extra burners

ADD MOVEMENT

Lunge, then bring your back foot through to lunge forward on the other leg. Keep going for 10 steps, alternating feet, then turn around and go back the way you came. Repeat twice more.

ADD WEIGHT

Perform walking lunges while carrying light dumbbells in each hand – start with 5kg and work your way up. Keep your arms straight down at your sides and don’t slouch your shoulders.

ADD JUMPS

Lose the weights and try jumping lunges. Lunge, then jump up, switching legs in the air, and land back in a lunge with the other leg in front. Aim for six on each leg, but stop if your form suffers.
