Doorway Biceps Curl

  • Beginner
  • Isolation
  • Rep-based

The doorway biceps curl is a bodyweight isolation exercise that uses your body's leverage against a door frame to target the biceps and forearms. It is an excellent equipment-free alternative for developing arm strength and improving the mind-muscle connection with the biceps.

  • Biceps

Equipment

  • Body weight

Setup

  1. Stand in a doorway and grip the side of the door frame with one hand at shoulder height using an underhand grip (palm facing you).
  2. Place your feet close to the base of the door frame.
  3. Lean your body back until your arm is fully extended, maintaining a straight line from your head to your heels.

How to do it

  1. Exhale and pull your body toward the door frame by curling your arm, focusing on bringing your shoulder toward your hand.
  2. Squeeze your bicep hard at the top of the movement for one second.
  3. Inhale and slowly lower your body back to the starting position using a controlled 3-second eccentric tempo.
  4. Perform all repetitions on one arm before switching to the other.

Form checklist

  • Keep your elbow pinned close to your ribcage throughout the movement.
  • Maintain a rigid core and straight torso; do not let your hips sag or lead the movement.
  • Ensure your feet remain planted and do not slide.
  • Use a full range of motion, fully extending the arm at the bottom without locking the elbow out aggressively.

Pro tips

  • To maximize the peak contraction, imagine you are trying to rotate your pinky finger toward your shoulder at the top of the curl.
  • Focus on pulling through the palm of your hand rather than just gripping with your fingers to better engage the bicep.

Make it harder

  • Move your feet further forward (past the door frame) to increase the lean angle and the percentage of body weight you are lifting.
  • Add a '1.5 rep' style by performing a full rep followed by a half rep from the bottom to the midpoint to increase time under tension.
