wanna ask something guys, about the dumbbells that the gym im working out in...

you see now i'm currently stuck at 20kg bells, and the next set of dumbbells is 60 lbs . ( examples like bench press, military press)

How am i suppose to progress? I'v tried the 60 lbs dumbbells, and it's too heavy for me but i dont wanna get stuck at 20kg for so long...
