If I wanted to build core strength I'd start with these five chair exercises for abs

Sit-ups and the plank are not the only ways to build core strength. As a personal trainer who holds chair workout classes for seniors, I've seen for myself how seated exercises can strengthen the abs and deep core, too.

The best thing about these exercises is that they're suitable for all ages and fitness abilities. Plus, strengthening your core can help protect the lower back, which can be affected by long periods of sitting.

How to do these chair exercises for abs

This seated workout has five moves using a resistance band to target and strengthen the core. All you need is a chair and a medium-strength resistance band.

Before beginning each move, engage your core, and keep your torso as still as possible.

The workout uses straight sets. So complete 8 reps on each side of the first exercise. That's one set. Rest for 30 seconds, then complete another 8 reps on each side. Continue in this fashion until you've completed three sets then move on to the next exercise.

One of the most effective ways to get stronger is to repeat workouts, making it a little more difficult each time. That's one reason why I've included rep ranges. After a day or two's rest, try the workout again, but this time with 9 instead of 8 reps. Once you've hit 10 reps, choose a band with greater resistance and start over again at 8 reps.

Why chair workouts are good for the core

You might assume that exercising in a chair is an easier workout, but actually it's a great low-impact way to strengthen the core. What I love about seated workouts is that when you do upper-body exercises, it forces the core to resist the tension in the band that is pulling you out of your seated posture.

Why I teach chair workouts

You can work the whole body during a chair workout, building quad and glute strength by doing seated leg lifts and banded hip openers, as well as shoulder mobility by doing arm extensions. Seated exercise is suitable for all ages and fitness levels, and in my opinion it's a great way to build strength gently.
