Weight-bearing exercises30 minutes on most days of the week. Do a 30-minute session or multiple sessions spread out throughout the day. The benefits to your bones are the same.
Muscle-strengthening exercisesTwo to three days per week. If you don’t have much time for strengthening/resistance training, do small amounts at a time. You can do just one body part each day. For example do arms one day, legs the next and trunk the next. You can also spread these exercises out during your normal day.
