Alternate Hammer Curl vs Zottman Preacher Curl

Stand up with your torso upright and a dumbbell in each hand being held at arms length. The elbows should be close to the torso.

The palms of the hands should be facing your torso. This will be your starting position.

While holding the upper arm stationary, curl the right weight forward while contracting the biceps as you breathe out. Continue the movement until your biceps is fully contracted and the dumbbells are at shoulder level. Hold the contracted position for a second as you squeeze the biceps. Tip: Only the forearms should move.

Slowly begin to bring the dumbbells back to starting position as your breathe in.

Repeat the movement with the left hand. This equals one repetition.

Continue alternating in this manner for the recommended amount of repetitions.

Grab a dumbbell in each hand and place your upper arms on top of the preacher bench or the incline bench. The dumbbells should be held at shoulder height and the elbows should be flexed. Hold the dumbbells with the palms of your hands facing down. This will be your starting position.

As you breathe in, slowly lower the dumbbells keeping the palms down until your upper arm is extended and your biceps are fully stretched.

Now rotate your wrists once you are at the bottom of the movement so that the palms of the hands are facing up.

As you exhale, use your biceps to curl the weights up until they are fully contracted and the dumbbells are at shoulder height. Again, remember that to ensure full contraction you need to bring that small finger higher than the thumb.

Squeeze the biceps hard for a second at the contracted position and rotate your wrists so that the palms are facing down again.

Repeat for the recommended amount of repetitions.
