Thanks PrinceVegeta, philosopher and ironheart for support.
Rocky: Yes, this was my first time when I did pushes with those weights so I didn't know how much I can lift. Next time I will start with 65 and if it's easy I will raise.
Mikew: Thanks for advice. I test it next time. I'am never lifted over 67,5kg so I don't know can I lift over 70kg :D. But it is possible that I lift ~75kg. That I test in this week.
Today I just pumpped biceps and abs with small weights so I don't write it up :D.
