Plank toe touch combo – PICTURE – Women's Health & Fitness

4. Plank Toe Touch Combo

1. Start in a full plank with your arms straight and under your shoulders, your back in line, and your hips even.

2. Engage your abs, and then gently move your left knee into your chest, across the other side and then extend the leg out to the side, touching the toe to the ground at a 45-degree angle.

3. Repeat this in reverse – toe touch, knee tuck, knee crossover and return to the starting position.

4. Swap sides and then repeat 10 to 15 times.
