Plank Knee-to-Elbow

What it is

From a high plank, bring one knee slowly toward the elbow on the same side, then return and switch. It is a slower, more controlled cousin of the mountain climber that also hits the obliques. Keep the hips level as the leg moves.

Technique tips

• Hold a straight line from head to heels
• Bring the knee to the outside of the same elbow
• Crunch the side of your waist
• Control the leg back to the start

How to track your progress

Log reps, and add the extra load if you wear a belt or a vest. Straddly counts your bodyweight in the estimated max, so added weight and extra reps both show up as progress, and new records are flagged during the session.
