Remember to push your buttocks out as you bend to maintain a straight back posture, and do not bend your knees past your toes. Once you're comfortable with that, try doing a half squat against a wall. This can be a more challenging move — especially if you get all the way into a seated position — so you may want to make sure you have someone there to assist you.
Since accidental falls are a significant source of injury for many older adults, incorporating balance exercises in your exercise regimen is essential. Doing balance exercises, such as the ones described here, or an activity such as tai chi or yoga, makes it easier to walk on uneven surfaces without losing balance. You can do these balance exercises every day, several times a day — even when you’re standing in line at the bank or the grocery store.
