In the dining room - hair dips

Sit on the edge of your bed or a sturdy chair with your palms planted on each side of your hips with your fingers hanging over the edge. Walk your feet out a little so that your hips are off the chair. Your bum should just clear the edge as you use your arms to lower yourself down.

Keeping your knees bent, lower your body until your elbows are at 90 degrees and your upper arms are parallel to the floor. Use your arms to raise yourself up and continue to raise and lower yourself 12-15 times. Do two to three sets. As this becomes easier, do the exercise with your legs straight. 

In the lounge - close-hand push ups

Kneeling down on all fours on a mat, place hands down in front of you, with your thumbs and index fingers touching. Raise your legs up behind you from the knee. Make a straight line between your shoulders, hips and knees and tighten your stomach muscles.

Slowly lower yourself towards the floor, aiming your chest towards your hands. Stop a few centimetres off the floor then push up again. Do between 12 and 20 reps.

In the kitchen - tricep kickbacks

Start with a small dumbell or substitute (such as a tin of tomatoes or a plastic bottle filled with water). Bend over at the waist, resting one hand on a chair, so that your back is flat. Grasping the weight in the other hand, bring your bent elbow up to your side and keep it there. This is your starting position.

Now, keeping your elbow close to your side, extend your forearm back until your arm is straight, then lower and repeat 12-15 times. Do two to three sets. You can increase the weight if it starts to get too easy.
