Sit on top of your balance board, feet flat on the floor, knees bent, hands grasping the back of your thighs, abs engaged, and back as straight as possible. While maintaining a flat back, lean back slightly while lifting your feet off the floor to balance on the board. Let go of your legs and extend your arms in front of you.
Breathe steadily as you balance in this seated position for 15-30 seconds. Gradually work your way up to holding this exercise for 1-3 minutes for an isometric core challenge.
Try to keep your legs together and your back flat at all times. Engage your abs and stare at a focal point in front of you to help with balance.
Make it harder: As you get better, try to lift your arms higher instead of extending them in front of you. The higher your arms are lifted (such as next to your ears), the more challenge you'll add to this exercise.
