Exercise Instructions

  1. Grasp a set of dumbbells and sit on the end of a flat bench with the dumbbells resting on your thighs.
  2. Lay back on the bench and extend your arms out, holding the dumbbells above your body with a neutral grip (palms facing each other). The dumbbells should not be touching. Keep your feet planted on the floor for balance. Bend your arms slightly. This is the starting position for the exercise.
  3. Slowly lower the dumbbells out to your sides in a semi-circle. Rotate at the shoulders only, keep your arms slightly bent.
  4. Once the dumbbells get about level with your chest, squeeze the chest muscles and raise the dumbbells back up using the same path of motion (semi circle) as you did on the way down.
  5. Without letting the dumbbells touch, slowly lower them again. 
  6. Repeat for desired reps.

​Dumbbell Fly Tips:

  1. This exercise should be done slowly, focusing on the stretch and contraction of the pectoral muscles.
  2. Don't pause or let the dumbbells touch at the top of the exercise.
  3. Use a full range of motion by lowering the dumbbells as far as comfortably possible.
  4. Always use a wide semi circle motion when doing this exercise, and don't allow the dumbbells to come too close to the body.

you may be holding the weight too close to your head. while laying on your back, bring the weight closer down to your feet, so the the weights are above the lower part of your chest, and on the decent, try to keep them in that general vicinity. you'll recruit more shoulder muscle fibers the closer the weight come to your head

You are feeling it more in your shoulders because 1. when you have the dumbbells together over you you cannot reach a peak contraction because of the position of your arms perpendicular to the ground thus a lot of the stress is transferred to your elbow joint, AND for peak contraction you need to cross your hands over and past each other over your chest. Drop the dumbbells and start using cable flyes so you can get that peak contraction. (which have the same resistance at the top as they do at the bottom, which dumbbells don't) 2. you stretch your hands too far out from your body during the lower, stretched position, which transfers more of the stress onto your anterior delts. Instead keep the bend in your elbow so that your forearms are always perpendicular to the ground. This allows a full stretch upon your pecs with the maximum stress. AND the 3rd and most important tip: ALWAYS maintain the correct form of keeping your shoulder blades back while performing chest flyes for maximum pec stimulation. Pretend you are trying to squeeze a tennis ball between your shoulder blades.

Additional tip #1. Instead of keeping your feet on the floor bring them up and place them on the bench as if you were going to do sit-ups on the floor position. This little technique (emphasized by the great Vince Gironda) helps place/keep the stress on the pecs.

Additional tip #2: Stop squeezing your hands so hard around the handles. Sounds strange, but try to keep your hands as loose as possible while still maintaining a safe & secure grip. It's the same as with using straps with dumbbell rows. Less stress upon the hands (straps aiding grip) = more muscle activation in the target muscle. Instead of having your thumbs touch your fingers when you wrap your hands around the handles, keep a small amount of space between them for better pec stimulation.

P. S. You're welcome ;-P

It sounds like you are using to much weight. That will cause you to put more emphasis on your shoulders than than your pecs. Try using less weight and see if it helps.

I agree with Chris, it sounds like too much weight. I've found that I can use heavier dumbbells, but after a few reps it puts strain on my shoulders so I have a tendency to bring my arms in closer to my body at the bottom of the motion. This reduces effectiveness as a chest exercise and can be corrected by using a lower weight with a slower controlled motion and more reps.

I`d recommend you to keep your shoulders back and down, basically. If you do flys on a bench, you need a spotter and need to make 100% sure that you don’t let your elbows drop lower than your shoulders as this would hyperextend your shoulder and put it at risk of injury. Like all exercises, the key is to do this exercise very slowly and with strict form – no cheating. Keep your arms straight but not locked, if you have to bend your elbows then use a lighter weight. Bend your knees and put your feet flat on the ground, this puts your lower back in a safe position. When lifting, flex your abs for additional lower back support. Form is everything, try for 2s up and 2s down. It is best to do dumbbell fly laying on the floor to safely limit your range of motion.

The best thing u can do it take the best guidance and do it properly,putting too much weight on any exercise won't help to build any muscle,begin with the low weight and get the maximum result,and its better to do the original exercise without cheating yourself rather than alternatives.

I currently bench 65kg for 8 reps. What would be a suitable weight for each dumbell?

Cheers!
