1. Lay on your back legs bent in the air 90 degrees, place hands gently behind head

2. Bring one elbow towards opposite knee as you extend the opposite leg, as you crunch.
3. Use your torso to twist.

Tip – the faster you go (with control) the easier, if you really want your obliques to shout at you in pain go slower.

Target = core (inner and outer obliques in particular)
