Is there a proper method to increase my chest strength?

I work out with my friends who could do bench presses much heavier than i do.

I push myself to lift their weights every time we work out together but after few weeks i'm still struggling with a lot of support from them.

Should i maintain to the weight i could manage or would lifting heavier weight help?

I'm taking ON whey currently but my diet is screwed

ok i'll stick to my own weights thx

i can lift it with support, i'm doing it for 4 sets.......or lifting without support would be better?
