If you just bought an ab roller and you’re having trouble doing it, don’t worry! It may take some time to get used to the movement. Try practicing on your back first, then roll onto your side. You can also start by doing a few reps on your back before trying the side version. If you’re still struggling after that, try holding onto a wall or stable surface for extra support until you gain more strength in your core muscles. Don’t force yourself to do too much too soon!
