Weeble Wobble & Yet I Still Fall Down

Yesterday's attempt at working out at the gym is a definite success. Here's what I have done thus far:
12 minute circuit using kettle bells
*Shoulder Press
*Kettle bell Swings
*Kettle bell Bicep curl
*Clean & Press
*Halos
*Deadlift
---This exercise required 50 second session on each set and repeated twice with a 10 second break in between.

Took a break for 20 minutes by doing cardio on the Cybex. I loathed the Cybex, but just like with any torture device so far, I begin to love it.
Went to the back extension bench and upped up my weight/reps by doing the following for lower back/glutes: 0 pounds for 25 reps, 10 pounds for 20 reps, 25 pounds for 15 reps, and 10 pounds for 10 reps.
Afterwards, I kept the same 25 pound plate to do 30 reps on each side for the obliques but for two sets instead of the usual three.
Abduction 50 pounds to 110 pounds in four sets and Adduction 50lbs to 80lbs for four sets. This exercise allowed me to realize my absolute weakness--inner thigh muscles.
All in all, this exercise was meant for abs, core, and legs. I was excited since I got the go ahead to work on my legs again. However, this break from lower body exercises allowed me to focus a ton on my core and my back/arms.

Because I finally got to work out my legs, it seems like half the time I am about to fall down. My legs are jello. Can't wait to go back to the gym to do more...
