TFW Sit Ups
To do the TFW Sit Up, lie on your back with your legs out straight in front of you and your hands in under your chin.
Then sit up, bringing your knees in as you move to place your hands on your shins. As you come to a tucked seated position, place your feet on the ground. Don’t swing your arms overhead to sit up. You can move your arms from in under your chin to around your legs at the top while you are seated.
Then lie back down, straightening your legs back out in front of you as you bring your hands back in under your chin. With this Sit Up Variation, you can release at the bottom and touch your shoulders and heels down.
Repeat, sitting back up as you bring your knees back in, grabbing your shins. Move as quickly as possible. As you sit up and lie back down, make sure not to arch your low back. Press it into the ground and feel your abs working.
If your low back takes over, try a Basic Sit Up or even a pelvic tilt progression.
