The 45 Degrees Arms Plank, also known as a long-lever plank, increases core demand by extending the lever arm, forcing the abs and obliques to work harder to prevent the spine from arching. This variation builds superior anti-extension strength and shoulder stability compared to a standard plank.

Setup
- Start in a standard high plank position with your hands directly under your shoulders and feet hip-width apart.
- Walk your hands forward approximately 12–18 inches until your arms are at a 45-degree angle relative to your torso.
- Ensure your body forms a straight line from your head to your heels.
- Engage your quadriceps and squeeze your glutes to stabilize the pelvis.
How to do it
- Inhale deeply into your diaphragm, then exhale and brace your core as if preparing for impact.
- Maintain a steady, rhythmic breathing pattern while holding the position, avoiding holding your breath.
- Keep your elbows locked and push firmly through your palms to engage the serratus anterior and pectorals.
- Hold for the target duration, then carefully walk your hands back to the starting position to finish.
Form checklist
- Do not let the lower back sag or the hips pike toward the ceiling.
- Keep your neck neutral by looking at the floor slightly in front of your hands.
- Maintain a slight posterior pelvic tilt (tuck your tailbone) to protect the lower back.
- Ensure shoulders stay depressed and away from your ears.
Pro tips
- Actively 'pull' your hands toward your toes without actually moving them to create maximum tension in the rectus abdominis.
- Focus on 'knitting' your ribs toward your hips to prevent the ribcage from flaring out.
Make it harder
- Walk the hands even further forward to transition into a 'Superman' plank.
- Lift one foot two inches off the ground to add a rotational stability challenge for the obliques.
