So Many Wonderful Ways to Work Your Abs With the Russian Twist

This is the best exercise for building up strength and flexibility to do the seated Russian twist. Since you are seated upright as you twist, this move is less taxing on the abs. It's also a great stretch for the hamstrings, and one of our go-to moves for warming up.

• Begin sitting on the floor with your legs stretched out in front of you; lengthen your spine to keep your back straight.
• Pulling your navel in tight, twist from right to left, lightly touching both hands from side to side to complete one rep/rotation.
• Start with 20 rotations per set.
