An isolation exercise that targets the quadriceps by extending the leg against cable resistance.

Instructions

  1. Set the cable pulley to the lowest position and attach a single cuff attachment or ankle strap.
  2. Stand facing away from the cable machine, securing the cuff around your ankle.
  3. Hold onto a stable structure for balance, keeping your torso upright.
  4. With a slight bend in your knee, extend your leg forward against the cable resistance.
  5. Pause briefly at full extension, squeezing your quadriceps.
  6. Return to the starting position in a controlled manner without fully relaxing the tension.

Tips

  • Maintain an upright posture and avoid leaning backward; keep your torso stable.
  • Ensure the cuff is positioned securely above your ankle for safety.
  • Extend your leg fully but avoid locking out your knee at the end of the movement.
  • Control the eccentric portion to maximize quadriceps engagement.
  • Use a weight that allows for full range of motion with proper form.
  • Perform equal repetitions on both sides for balanced leg development.

Recommended starting values

Sensible novice starting points for each goal, for a lifter aged 25–40. Scale down for smaller frames or older lifters. Treat the first set of any session as a discovery set.
