Go down slow, tap chest on the ground, then push up fast. Scale if needed on the way up (use knees or arch back). Return to tall plank with strong form and repeat. Always try to maintain form (core tight, hips tucked) on the way down. If possible, maintain form on the way up as well.
Option to complete this exercise from a short plank (elbows on the ground) if you’re experiencing wrist discomfort.
The knee raise balance can be completed on the floor. For a more advanced version, stand on a balance cushion or bosu ball. Hold a weight for extra emphasis on core stability.
