- Start in a side plank on your left side (no slider or towel needed) with your left elbow resting directly under your shoulder and your hips stacked. To make the move more challenging, you can place a Pilates ball under your right hand.
- Pull your right knee into your chest and hold for one to two seconds before tapping your leg back in the starting position. Keep your body lifted at all times by engageing your obliques.
- Do eight to 12 reps before switching sides.
