A Personal Trainer Shares 4 Gentle Seated Exercises That Safely Improve Core Strength in Older Adults

I work with many clients who are 65 and older. Some of them struggle to get down on a yoga mat for regular floor exercises. But that does not mean we skip core work completely. Ab training remains important even when we need to modify the movements. A strong core is valuable at any age but it becomes particularly crucial for seniors. Core muscles like the transverse abdominis and internal obliques help with breathing and posture and balance. These areas often matter most to older adults who want to remain active and independent. When I train someone with mobility challenges I use these four seated exercises in their core strengthening program. Even if you can exercise on the floor easily these movements can add variety and present a fresh challenge to your abdominal workouts.

Before starting a new fitness routine, it’s essential to check in with your medical team. Working alongside a certified personal trainer is also highly recommended, particularly if you’re new to exercising. A qualified professional can help fine-tune your form and offer appropriate adjustments or alternatives when needed.

Aim to complete each movement for 1–3 sets of 10–15 repetitions. Beginners should start with fewer reps and sets, then gradually build up as strength and confidence increase.

Why Seated Core Exercises Are Beneficial

This chair-based routine targets essential core muscles such as the rectus abdominis, internal and external obliques, and the transverse abdominis. These muscles play a key role in stabilizing the body, supporting internal organs, assisting vital bodily functions, and maintaining proper posture.

Many standard core workouts require getting down on the floor, which may not be practical for individuals with mobility limitations or certain injuries. Because these exercises are performed while seated, they are accessible to a wide range of fitness levels and can be safely modified or progressed with guidance from a qualified personal trainer or physical therapist.
