Progress?

My workouts have been going well- I'm making nice strength gains and I feel much more springy.  Unfortunately, my vertical has remained the exact same.  I'm consistently touching the rim but nothing up from there.  It seems that I'm going to need to do alot more max jumping as my body apparently doesn't know how to use the new strength.

I did some new hip flexor lifts and leg curls\leg extensions before my squat and deadlifts last night.
It seemed to make both much easier.

Hopefully I'll suddenly shoot up a few inches in a week here soon.
