If I may point out that the D/B bench press done by the woman in the video has a lot to be desired. As the elbows are too close to the sides whendoing the exercise, so the effect on the pectoral muscles was very minimal.
In Danny Odell's comment it is suggesting that the dumbell exercise is usually light, of course this is not the case at all. I myself would prefere to do heavy dumbell press than with the barbell as it usally evens up the strength of both arms and the one arm dumbell also strenghtens up the core.

I don't really know what it is all about. I had to attend and addiction treatment lately and I didn't time to get in touch with any kind of news.

I do both barbell bench press and barbell dumbbell bench press. Both has its own advantages - dumbbell benches allows you to work each side of the chest independently and they incorporate more stabilizer muscles whereas barbell benches will allow you to lift more weight. hookahs

Steps:

1- Sit on the edge of a flat bench with dumbbells on your knees. Lie back.
2- Your palm should face forwards. Bend your elbows at a 90 degree angle so that your upper arms are parallel to the ground. hookah
3- Press the weights up over your chest in a triangular motion until they meet above the centerline of your body.
4- Make sure you keep the weights balanced and under control. Exhale as your arms go up. hookah bar
5- Then, follow the same path downward in a slow and controlled fashion. Inhale when you are doing this. hookah bars
