You'll get it in no time and you'll be pushing 100# and more 
One thing I found about learning a push press was that whenever a press gets hard, it seems to turn into a push press
It is like "hey I can get this weight up, just let me use my knees". I have to conscientiously avoid doing that.




Yay Mel
