Common mistakes with leg curls, machine (seated)

  • Too much weight: too much weight will prevent you from performing the exercise correctly. This reduces the training effect and increases the risk of injury. 
  • Momentum: If you move the weight with momentum, you relieve the target muscles and thus reduce the training effect.  Consequently, you should avoid swinging movements and get the strength isolated from the m. quadriceps femoris.
  • Incorrect seating position: When choosing the seating position, the knee joint axis has to be aligned with the machineĀ“s rotation axis. Adjust the seat cushion carefully to avoid knee injuries.
  • Wrong position of the foot roll: The foot roll should press against your lower shins just above the feet. Make sure the position doesn’t slip
