Instructions
Alternate Hammer 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.
Lying Supine Dumbbell Curl
Lie down on a flat bench face up while holding a dumbbell in each arm on top of your thighs.
Bring the dumbbells to the sides with the arms extended and the palms of the hands facing your thighs (neutral grip).
While keeping the arms close to your torso and elbows in, slowly lower your arms (as you keep them extended with a slight bend at the elbows) as far down towards the floor as you can go. Once you cannot go down any further, lock your upper arms in that position and that will be your starting position.
As you breathe out, slowly begin to curl the weights up as you simultaneously rotate your wrists so that the palms of the hands face up. Continue curling the weight until your biceps are fully contracted and squeeze hard at the top position for a second. Tip: Only the forearms should move. Upper arms should remain stationary and elbows should stay in throughout the movement.
Return back to the starting position very slowly.
Verdict
Both exercises target the biceps. Alternate Hammer Curl is a beginner exercise using dumbbell, while Lying Supine Dumbbell Curl is beginner and uses dumbbell.
