What are good exercises for abdominal muscles in a senior over 100?

A person’s core is composed of their rib cage, pelvis, and hips. These muscles support your spine. Throughout life, people lose their strength and muscle mass. Additionally, they tend to sit for more extended periods and do not use those crucial muscles in the core as often.
Seniors must maintain their core strength to prevent injuries and live a long and healthy life. All your daily activities require the core muscles to function correctly. The core is involved in lifting, walking, and climbing stairs. This is what stabilizes your body and directs limb movement.

Core Exercises for Stability
The best thing you can do for your health is maintain a strong core. It is simple to learn the best core exercises, and you don’t need a gym membership to do so. You require a sturdy chair and a little bit of time every few days.

Chair Planks
You can strengthen the deep muscles in your core by doing planks. Unfortunately, these muscles are hard to target. However, the feeling of bringing your belly button in and engaging your inner, deep muscles can contribute to the development of these muscles. As a result, you will be more aware of your body and posture.

Equipment needed
A sturdy chair, such as a kitchen table chair, is required for this movement.
Muscles worked
When performing planks, we strengthen and stabilize our transverse abdominal. You have these muscles wrapped around your spine, located low in your trunk. The rectus abdominis muscles (the six-pack muscles) are located beneath them and protect the spine.
Take It to the Next Level
As your chair planks become more accessible and you can hold the position for a minute or longer, you can start to do planks on the floor.

Seated Knee Lifts
Seated Knee Lifts are gradual exercises. No matter your fitness level, they can strengthen your core. This exercise promotes balance improvement and helps develop low abdominal strength as a single-sided movement.
Equipment needed
A sturdy chair, such as a kitchen table chair, is required.
Muscles worked
Knee lifts work your lower abdominal muscles and your transverse abdominal. These exercises encourage core stability.
Take It to the Next Level
Try this movement in a standing position once you gain strength.

Oblique Side Bends
As a result of incorporating this movement into your exercise routine, your trunk and core will be more stable and your spine supported. This movement can also benefit you when you do other daily activities.
Equipment needed: a sturdy kitchen chair.
Muscles worked
You have obliques as the muscles that run up the sides of your trunk. The supporting structure of your core relies heavily on these parts, but they are often overlooked.
