How to do it
How to do the inchworm.
Repeat slowly for about 45 seconds. Bend your knees as much as you need, and stop the walk-out before your back sags.

Step 1
Fold forward
Stand with feet hip-width apart. Fold forward and bend your knees enough to place your hands on the floor in front of your feet.

Step 2
Walk your hands out
Keep your feet in place and walk your hands forward one at a time. Lower your hips gradually as your hands move away from your feet.

Step 3
Find a steady plank
Finish with palms under your shoulders, legs long and toes tucked. Brace gently to keep your body steady without letting your lower back sag. Pause for a breath.

Step 4
Walk your feet in
Take small steps with your feet toward your hands, lifting your hips as you go. Soften your knees as needed, then stand tall. Repeat slowly, resetting your position when you need more space.
