3. Russian twist
Important Note: If you have a back injury then avoid doing this workout.
This is probably the most famous workout in this routine. It's very powerful for targeting your lower ab and obliques.
If you want to take things to the next level then you can add a 15 pound for more resistance.
But if you're just starting out don't use any weights as yet until you master all of the move.
How to do it
- Sit down on your glutes while leaning your upper body slightly backwards but not too far.
- Now you're going to twist your upper body around to the right as far as possible while contracting your abs.
- Then twist around to the left while still maintaining the contraction in your abs.
