If the cold winter weather has had you chilling on your bum a little too much and exercising a little too less, we've got five wicked moves to help bust your butt into shape!

The Squat
Stand with your feet shoulder-width apart, and slowly lower your body as though you're sitting in a chair until your thighs are parallel with the ground. Make sure you keep your weight in your heels, and slowly push yourself up until you're back to where you started.

Kick backs
On your hands and knees, extend one leg straight back and touch your toe to the floor. Raise your leg as high as you can, then slowly lower and repeat.
2-3 sets of 12 to 16 reps, 2 times a week

Pelvic Lifts
Lie on your back with your knees bent and feet on the floor. Keep your arms by your sides and then slowly lift your bum off the ground and push your pelvis toward the ceiling. Be sure not use your shoulders or back to pull yourself up. Hold for 10 seconds, then lower yourself down slowly, using your thigh and bum muscles.

Lunges
Although they're not very fun, lunges give serious results! Stand with your feet together and slowly lower your body into a lunge position, keeping the front knee and back knee at 90 degrees. Keep the weight in your heels, and slowly push back up to the starting position. Never lock your knees at the top and don't let your knee bend past your toes. Keep your torso tight and upright - no hunching!

Bum lifts
Lie on your tummy, with your head resting on your arms. Keep your legs together and slowly lift your legs up, pointing your heels towards the ceiling. Hold your legs in this position for three to five seconds, then slowly lower your legs back to the starting position.
