If you thought that was just inevitable with old age, I've got some great news. As we all know, one way to prevent bone loss is to eat calcium and vitamin D-rich foods like dairy products and green veggies. You can do more, though. While strength training will make you look buff in your bikini, doing weight-bearing exercise will also increase your bone density. Strong, sturdy bones help you keep your height and prevent a bulging back.
It's recommended to complete at least two strength training sessions a week. If you're a beginner, try this routine, and if you're ready for more of a challenge, give this head-to-toe workout a go. You may also benefit from doing specific exercises that strengthen the back, so try these moves.
