This quick workout allows you to build up the muscles in your trunk.

 While standing core exercises are ideal for building core strength, seated exercises are an excellent alternative for older adults to train their core if they have mobility or balance issues, injuries or other health issues that may be keeping them off their feet.

 "Our core is what stabilizes our entire body and connects our upper and lower limbs. Even seated, core strength exercises are beneficial," says Tina Tang, CPT, a New Jersey–based personal trainer who specializes in healthy aging.

 For example, older adults who recently had hip replacement surgery may not be comfortable standing for long periods of time just yet. Doing seated core exercises helps strengthen their trunk muscles to support their recovery.

“While recovering from hip replacement surgery, staying seated during a core workout allows someone to move without putting too much strain on their hip joints,” Tang says.

 Whether you have a health condition that makes it difficult to move standing, or you're easing back into a regular workout routine, consider this 20-minute seated core workout.

 Do 3 sets of 10 reps for each of the moves. Just like any strength workout, it's ideal to do this seated core workout at least twice a week — with the overall goal of training your core three times a week, Tang says.
