I have been working out for 1.5 years now.
For chest bench press(with a barbell), I do
10(rep)x30(kg) 10(rep)x40(kg) 8(rep)x50(kg)
I feel quite a pain in my front delts while doing and for 2 days after.
In contrast, if I do the it with a chest machine as shown in the picture, I can lift more weight also (can go around 70-80 kg for 3rd set) and I don't feel any pain(soreness) in delts later.
So, can I continue doing it with machine itself?
What's wrong with my barbell bench press?
