Dumbbell Single Arm Floor Press

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

This unilateral variation targets the chest and triceps while building core stability by resisting rotation. The floor provides a hard stop that protects the shoulders and emphasizes the lockout phase of the press.

Muscles worked

Primary

  • Pectorals

  • Abs

Equipment

  • Dumbbell

Setup

  1. Lie flat on your back on the floor with your knees bent and feet planted firmly.
  2. Hold a dumbbell in one hand with your arm extended toward the ceiling.
  3. Lower the weight until your upper arm rests on the floor at a 45-degree angle from your torso.
  4. Place your non-working arm flat on the floor out to the side for balance.

How to do it

  1. Exhale as you press the dumbbell straight up until your arm is fully extended but not locked out.
  2. Squeeze your chest and triceps at the top of the movement for one second.
  3. Inhale as you lower the weight under control until your tricep lightly touches the floor.
  4. Pause briefly at the bottom to eliminate momentum before starting the next rep.

Form checklist

  • Keep your lower back pressed firmly into the floor throughout the set.
  • Ensure your wrist stays stacked directly over your elbow.
  • Avoid letting your shoulder roll forward off the floor as you press.
  • Maintain a 45-degree angle between your elbow and your ribs to protect the shoulder joint.

Pro tips

  • Drive your heels into the floor to create a stable base and prevent your body from tilting toward the weighted side.
  • Focus on 'pushing yourself away from the floor' rather than just pushing the weight up to increase pectoral recruitment.

Make it harder

  • Perform the press while holding a glute bridge to engage the posterior chain and further challenge core stability.
  • Implement a 3-second eccentric (lowering) phase to increase time under tension.
