Sit-up haters, we've got a sit-up free workout ready and waiting for you to use—but if you love sit-ups, feel free to tack them onto the end of this five-move bodyweight routine.
The one thing we would advise acquiring before getting stuck into the core workout is an exercise mat (such as one of the best yoga mats), this adds a little extra protection for your back and joints during a floor-based routine like this one.
Developed by trainer Cindy Yu, this workout is all about challenging the muscles in your core to strengthen and tone your midsection. It's an equipment-free session so you can take these moves with you to the gym, on vacation, or just enjoy doing them from the comfort of your own home.
Let's take a look at the exercises, learn from Yu's demonstrations and explore some the benefits of the core building session.

You'll spend 30-45 seconds on each exercise and make sure you spend this amount of time on each side of the body per move. The aim is to complete four to five rounds in total but depending on how regularly you train your core, you may need to allow yourself short breaks to help you finish the full workout with proper form.
These are the moves you'll need for this short workout, but if you're new to any of them or could use a refresher, you can check out Yu's demonstrations on Instagram before getting started.
- Plank knee drive pike
- Curl leg kick out
- Bear pose rotate and reach
- Reverse plank knee in leg lift
- Kick out leg extension
There's nothing wrong with sit-ups — in fact, they're great for targeting your rectus abdominis (the 'six-pack' muscle). However, we understand that they can get a bit repetitive when they frequently appear in many of the best ab workouts.

The good news is, you aren't losing out on any core gains by ditching the sit-ups and instead giving Yu's five move routine a shot. Her collection of exercises engage various muscles in the core, including the obliques, transverse abdominis, and lower back.
The more muscles in the core you engage, the greater strength gains you can make, and you can improve things like stability and posture. And this has practical benefits, too, as it's no secret that a strong core is the unsung hero of good posture.
A bit like how a well-built building relies on strong foundations, the core muscles are the foundation of your mid and upper body. In strengthening the muscles of your abdomen, lower back, and pelvis, you can create a robust framework that keeps your spine aligned and prevents slouching or overarching.
