Decline Diamond Push-Up

  • Intermediate
  • Compound
  • Rep-based
  • Chest
  • Shoulders
  • Upper arms
  • Waist

This advanced push-up variation shifts significant body weight onto the upper chest and triceps by combining an elevated foot position with a narrow hand stance. It is highly effective for building triceps density and targeting the clavicular head of the pectorals.

Setup

  1. Place your feet securely on a bench or elevated platform with your toes tucked.
  2. Position your hands on the floor directly under your chest, forming a diamond shape with your thumbs and index fingers touching.
  3. Extend your legs and engage your core and glutes to create a straight line from your head to your heels.

How to do it

  1. Inhale as you lower your chest toward the center of the diamond shape, keeping your elbows tucked close to your sides.
  2. Lower yourself with a controlled 2-3 second tempo until your chest is just an inch above your hands.
  3. Exhale as you push back to the starting position by driving through your palms, focusing on squeezing your triceps and chest.
  4. Maintain a neutral neck by looking at the floor slightly in front of your hands.

Form checklist

  • Keep your hips level with your shoulders; do not let your lower back sag.
  • Ensure your elbows stay tucked at a 45-degree angle or less to protect the shoulder joints.
  • Maintain the diamond hand shape throughout the entire range of motion.
  • Keep your core braced as if preparing for a punch to stabilize the spine.

Pro tips

  • Imagine trying to pull your hands together toward the center of the floor to increase the intensity of the pectoral contraction.
  • Focus on a full lockout at the top of the movement to maximize triceps engagement and peak contraction.

Make it harder

  • Incorporate a 2-second pause at the bottom of the rep to remove elastic energy and increase time under tension.
  • Slow down the eccentric (lowering) phase to 4-5 seconds to further challenge muscle fiber recruitment.
