Boat pose is one of the best yoga poses you can do to strengthen your core, and here's a variation to make it even harder.
- Begin sitting on your mat. Lift your knees up to your chest, balancing with your shins parallel to the floor.
- Keep your spine long and your chest high, holding for one inhale and one exhale.
- Straighten your legs, and hold for one inhale and one exhale.
- This counts as one rep.
- Repeat for a total of 20 reps.
