What are dumbell flye exercises?

Answer 1

They are AWESOME! I love doing these. Here is a description from BodyBuilding.com (they have a video showing it on the site):

"Sit down on a flat bench with a dumbbell in each hand. Then lie back, keeping the dumbbells close to your chest. Lift the dumbbells over your chest by extending your arms. Maintain a slight bend in your elbows. Keep your hips and shoulders flat on the bench and your feet on the floor. Lower the dumbbells to the sides of your body in an arc-like motion. At the lowest point, your bent elbows should be on a horizontal plane even with the bench. Slowly bring the weights back up over your chest in an arc. The bend in your elbows should stay the same throughout the exercise."

Answer 2

Execution:

Grab the dumbbells and sit on a flat bench. Rest the dumbbells on your knees. Rock back so you are lying flat on the bench and use your knees to help you get the dumbbells into position.

Push the dumbbells up so they are directly over your upper chest.

With your arms bent at the elbows and palms facing each other, lower the weights in an arc until you fully stretch your chest.

With force, move the dumbbells in an arc over your chest until they touch.

Repeat until you complete your desired reps.

Answer 3

While lying on a bench holding the dumbbells at arms length with a slight bend at the elbow, raise the dumbbells to the top. Keeping full tension upon the pectorals at all times.
This exercise works your Chest, Triceps, Anterior Deltoid (Shoulder, Arms).

Answer 4

You lie on a bench and with one dumbbell in each hand, you extend your arms out and lift the weight from the floor all the way up until your hands touch. Use light weight at first.

This is for your chest muscles.
