Flexor digitorum superficialis

The flexor digitorum superficialis is a muscle that flexes the fingers. To engage this muscle, perform exercises that involve finger flexion.

  1. Start with your hand open and fingers extended.
  2. Slowly curl your fingers inward towards your palm.
  3. Hold the flexed position for a moment before returning to the starting position.

How to perform the Flexor digitorum superficialis

  1. Set up. Set up in a stable, balanced starting position appropriate for the Flexor digitorum superficialis using your body weight.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your forearms.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your forearms rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
