This elevated variation of the mountain climber reduces upper body strain while emphasizing oblique engagement through a rotational knee drive. It builds core stability and shoulder endurance, making it an excellent entry-level compound movement for the midsection.

Setup
- Place a stable, padded stool or step on a non-slip surface.
- Place your hands shoulder-width apart on the edges of the stool, ensuring your wrists are directly beneath your shoulders.
- Step your feet back into a high plank position, creating a straight line from your head to your heels with feet hip-width apart.
How to do it
- Exhale and drive your right knee across your body toward your left elbow, rotating slightly through the hips to engage the obliques.
- Inhale as you return your right foot to the starting position with control, avoiding any hip sagging.
- Repeat the movement on the opposite side, driving your left knee toward your right elbow.
- Maintain a steady, controlled tempo, focusing on the quality of the core contraction rather than speed.
Form checklist
- Keep your back flat and core braced; do not let your lower back arch or hips pike up.
- Maintain a strong push through the stool to keep your shoulders active and stable.
- Ensure your knee travels across the midline of your body to maximize oblique activation.
- Keep your gaze slightly ahead of the stool to maintain a neutral neck alignment.
Pro tips
- Think about 'crunching' your ribcage toward your opposite hip at the peak of the movement for maximum muscle fiber recruitment.
- Keep your weight shifted forward over your hands throughout the set to keep the tension on your deltoids and abs.
Make it harder
- Hold the knee-to-elbow position for 2 seconds to increase time under tension and isometric core strength.
- Perform the movement with a 'double pulse' at the top of the rotation before switching sides.
