1-This is also a great chest isolation dumbbell workout. First lie down on your back on a flat bench holding a dumbbell in each hand. Hold the weights with arms straight on top of your chest elbows slightly bent.
2-Slowly lower them opening up your chest stretching the muscles practicing a fly like movement. Keep your arms rigid throughout your set and squeeze on the way up like you are hugging something between your chest and stretch on the way down.
3-Note the movement is similar to an incline dumbbell fly but instead of bringing you arms together in a straight regular fly motion you are doing the dumbbell flies in a V motion. Please see picture for correct form!
