HOW TO PERFORM - JACKKNIFE

The jackknife core workout is a great exercise for targeting your abs and strengthening your core muscles.

🤞Remember to engage your core muscles throughout the exercise and to keep your movements controlled and steady. Start with a few repetitions and gradually increase as you build strength.
