Sit in an upright chair - preferably a dining chair (not your riser recliner chair) with your legs bent and your feet on the floor. Slowly lift one knee at a time up towards your chest, pulling the tummy in at the same time and then return your leg to the floor. Repeat as many times as is comfortable and then repeat with the other leg. Do 2 sets of the same amount of repetitions for each leg and gradually increase the repetitions and sets as you feel stronger. This exercise will work both your abdominal and leg muscles which helps to keep your legs strong and aids with standing and walking for longer periods.
This exercise is very similar to the knee lift but the leg is then extended fully, with toes pointing upwards, returning to the floor when done. Again, do as many as is comfortable with each leg - say start with 6 or 8 and gradually increase the repetitions and sets as your strength is increased. This exercise works the upper thighs and buttocks aiding your ability to move around well.
Start by sitting upright in your chair with arms by your side, then with the palms of your hands forward and keeping your shoulders down, lift both of your arms out to the side and then upwards as far as you can comfortably do. Then return your arms to the starting position. Repeat as many times as is comfortable and start off by doing a couple of sets, increasing sets as you feel fit. This exercise could be done with light dumbbells or even with a tin of beans in each hand if you feel you can. Doing this exercise will strengthen your shoulders.
Sit upright with feet flat on the floor. Cross your arms and touch your shoulders with your hands. Keeping your hips still, turn your upper body to one side as far as you comfortably can and hold for 5 seconds. Return and repeat on the other side. Again, do as many as is comfortable for you and increase the reps and sets as you become stronger. This exercise will help to strengthen flexibility in the upper back and abdomen. These core muscles are used for example when getting in and out of bed and when bending over to pick things up, they also play a big part in maintaining balance.
Place a ball or rolled up towel between your knees and squeeze your legs together, release and repeat as many as you feel like doing, it’s as simple as that. This exercise will increase strength in the inner thigh muscles, which will help with your stability and flexibility.
