Exceeded my dumbbells on the press- I've got a pair of 30 lbs, which I'm now able to do 30 reps/set. Since I'm not going to be able to afford heavier weights anytime soon, I'll probably start doing compound exercises and complex movements to up the challenge.

I've just reached the basic comfort level with them on other exercises (saws, butterflies, etc.) and almost comfort with shoulder presses. I plan on taking up squats and, at least using my lower set (10lbs) for some knee lunges until stabilizers get stronger.
