Before working your abs, Ryan and Eric said it's a good idea to properly sequence your breathing. This exercise engages your diaphragm, which is another key part of your core. Here's how to do it:
- Lie on your back with your knees bent and feet flat on the ground.
- Place the first two fingers of your hands just above your hip flexors, on either side of your body.
- Inhale deeply through your nose, feeling the air flow through your belly and making your fingers rise. Hold the breath for one to two seconds.
- Exhale forcefully through your mouth. Feel your abs contract and your fingers sink.
- Repeat three to six times, then rest for one to two minutes. Complete three sets total.
