20-minute workout

Mountain climbers
Start with your feet on the floor as well as both hands. Bring your knees into your chest one at a time as quickly as you can. Aim for 30 repetitions in 15 seconds, 40 in 20 seconds, and 60 repetitions in 30 seconds.

Plank spiders
Place all your bodies weight on your elbows, and have your feet on the ground hip width apart. Bring one foot up of the floor and drive your knee as high up the side of your body as you can. The arch of your foot should be parallel to the floor.

Press ups with feet on chair
Place your feet on a chair and make sure there is a straight line between your ankles. Hips and shoulders. Lower your chest until it touches the floor and straighten your arms to return to the start position. Your arms should be shoulder width apart throughout the press up.

Walking lunge
Step forward and make sure that as you bend your knees that both your legs are close to a 90-degree angle. When you straighten your leg to stand up move your back leg forward and place it a few feet in front of you and lunge down. Your back leg becomes your front leg, and you want to repeat this for the full 30 seconds.

Triceps dips on chair
Place your hands on the chair with your hand fingers facing in a forward direction. Keep your back close to the chair and start with your arms straight. Bend your knees so that your bum moves closer to the floor and that your arms are at 90 degrees bend. Straighten your elbow joint to raise your bum and body up.
