My Latest Killer Workouts

Lately I have been doing these killer workouts from bodybuilding.com.  They aren't meant to make you huge to be a body builder, just good hard workouts that will kick your butt.  Basically I do 4-6 exercises per day (4x per week) and I do 3 sets of 8-12, I am suppose to keep the weight at a point where that is all I can do, not a rep more.  So far so good, I have done pretty well and paid the price the next day each time with being sore and tired.  I am pretty excited about it overall, but can't help but realize that my numbers are SO much lower than what I did in college.  Now for me, I graduated college 7 years ago, its so insane to think that by the way, because I remember it so clearly.  During college I loved the gym, a lot of my friends came from hanging out the gym and I had a fabulous workout partner that would not allow me to quit, skip or anything else, it was GREAT!  My 1 rep maximum's were fantastic too, my bench was around 180 in my junior year, which was definitely my best year as far as lifting went!  Now I am struggling at around 80 pounds, now granted I am not just doing 1 rep, I am trying to do between 24 and 36 of them but still its quite the jump.  So I have decided one of my goals is to get a 1 rep max of at least 150 back.  I would like to do this by the end of the year, so hopefully these workouts that really push you hard on the weights will help.

As of right now I am just eating healthy and not following their nutrition program.  I am also not doing their version of cardio, but mostly because I enjoy classes at my gym and playing volleyball for most of my cardio.
My other "fitness" goals are: to be able to run a half marathon, to lose weight (i'll spare you the number) and of course to get my lifting numbers up!

On a complete side note, yesterday I was lifting (calf raises to be specific) and picked up 40lb dumbbells, and the guy working out near me was like are you sure you can lift those? It's always a nice feeling to show a guy you can lift nice and heavy weights!
