This move is a killer for abs and core! Practise regularly and you’ll progress quickly.
Lie on your back and extend your legs. Avoid placing your hands under your glutes and instead push your belly button down and spine towards the ground. Focusing on keeping the back planted on the ground.
Squeezing your abs and glutes at the same time will help you stay strong.
Raise your legs to 90 degrees and slowly lower them towards the ground, pausing just above the ground or at the point before you need to let them fall.
Keep practising this one as you can progress really quickly.
