Step-by-step instructions

Follow these cues to master proper technique and stay safe through every rep.

  1. Step 1Setup
    • Adjust the seat height of the preacher curl machine so that your upper arms rest comfortably on the pad.
    • Select an appropriate weight on the machine that allows you to perform the exercise with good form.
  2. Step 2Position Your Arms
    • Sit down on the machine and place your upper arms against the pad, ensuring your elbows are slightly below shoulder level.
    • Grip the handles or bar with an underhand (supinated) grip, keeping your hands shoulder-width apart.
  3. Step 3Engage Your Core
    • Sit up straight with your back against the backrest and engage your core muscles.
    • Keep your feet flat on the floor and your legs comfortably positioned.
  4. Step 4Curl the Weight
    • Begin the movement by curling the weight upward towards your shoulders, bending at the elbows.
    • Keep your upper arms stationary against the pad and focus on using your biceps to lift the weight.
  5. Step 5Squeeze at the Top
    • At the top of the movement, squeeze your biceps for a moment to maximize the contraction.
    • Ensure that you do not lift your upper arms off the pad during this phase.
  6. Step 6Lower the Weight
    • Slowly lower the weight back down to the starting position, fully extending your arms while maintaining control.
    • Avoid letting the weight drop quickly to prevent injury and to keep tension on the biceps.
  7. Step 7Repeat
    • Repeat the curl and lower for the desired number of repetitions, maintaining proper form throughout each rep.
  8. Step 8Finish the Exercise
    • After completing your reps, carefully place the weight back on the machine.
    • Stand up from the machine, ensuring you do so safely and without rushing.
