Why I do it: Also known as AbMat sit-ups, we usually place an AbMat cushion under our lower back when doing this move. It works the upper, middle, and lower abs, and is a great way to strengthen the abs when learning toes to bar.
- Lie on your back, and open your legs into a diamond shape (aka butterfly legs) with the soles of your feet pressed together and knees out wide. Extend your arms overhead.
- Inhale to curl your torso up, and tap the floor in front of your feet to stretch your glutes a bit.
- Slowly lower back to the starting position.
- This counts as one rep.
