Knee to High Plank

This exercise strengthens the core, shoulders and arms. Because it is weight-bearing through the hands, it is also good for the arm and wrist bones.

Begin on hands and knees on a mat.

Keep your abdominals drawn in and engaged as you step one foot back and then the other to form a plank. Hold this plank for 1-3 seconds, then return to the starting position on your hands and knees.

• Keep your arms straight and your shoulder blades engaged throughout the movement, like you're pushing the floor away from you.
• Keep your trunk steady as you move between positions.
• Don't let your hips sway from side to side.
