Sit-up
Muscles worked: Abs
Coach tip
Lift with your abs, slowly, without pulling on your neck.
How to do it
- Lay your phone on the floor on its side and lie down side-on to it - it needs to see your torso and your knees.
- Lie on your back with your knees bent and feet flat, heels close to your hips: the raised knee is the reference the count uses.
- Curl up until your shoulder blades leave the floor, keeping your lower back down, then lower slowly - the full lower-down counts as a rep.
Where to put your phone
phone lying on the floor on its side, about 2 meters away - the screen needs to see your whole body side-on, from head to toe.
