Exercise guide

Suspender Front Plank

  • Intermediate
  • Compound
  • Timed hold
  • Waist

The Suspender Front Plank utilizes the instability of suspension straps to significantly increase demand on the core and shoulder stabilizers compared to a traditional plank. It is highly effective for developing isometric strength in the abs and obliques while engaging the pectorals and deltoids to maintain a steady base.

Muscles worked

Primary

  • Abs
  • Deltoids
  • Obliques
  • Pectorals

Secondary

  • Erector spinae
  • Serratus anterior

Equipment

  • Suspension trainer

Setup

  1. Adjust the suspension trainer so the foot cradles are at mid-calf height.
  2. Place your feet or toes into the cradles while facing away from the anchor point.
  3. Position your forearms on the floor with elbows directly under your shoulders, or place your palms flat for a high-plank variation.

How to do it

  1. Exhale and lift your knees off the floor, extending your legs until your body forms a straight line from head to heels.
  2. Engage your core and glutes immediately to prevent the straps from swinging.
  3. Maintain a steady, controlled breathing pattern, inhaling through the nose and exhaling through the mouth while holding the position.
  4. Hold for the target duration, focusing on keeping the straps perfectly still.

Form checklist

  • Do not let your lower back sag or your hips hike upward.
  • Keep your shoulder blades pulled apart (protracted) rather than letting them collapse together.
  • Maintain a neutral neck by looking at the floor slightly in front of your hands.
  • Ensure your weight is distributed evenly across your forearms or palms.

Pro tips

  • Actively push your heels back into the handles to create more tension throughout the posterior chain and stabilize the straps.
  • Focus on 'knitting' your ribs toward your pelvis to maximize the contraction of the rectus abdominis.

Make it harder

  • Suspension Body Saw: While maintaining the plank, slowly push your body backward a few inches using your shoulders, then pull back to the start.
  • Suspension Mountain Climbers: Alternately draw one knee toward your chest while keeping the other leg extended and stable.
