You're at the gym, it's your first workout in a long time. After warm up, which exercise do you do first?

I go for whatever is free.

I stay home and do basic weight lifts and/or exercises.

Or go for a run. People at gyms are weird.

I alternate upper/lower(including abs). Start with the core lifts and work your way out

Why is there no deadlifts on that poll? Would go squats next

Question, I'm going to start going to the gym and I was wondering if I should work on cardio exclusively before weights or a mixture of both?

After the way I've been eating for the past two weeks I am pretty much exclusively hitting the treadmills for awhile.

I usually spend 20 minutes in the bike before doing any other exercise, so I guess that doesn't count as "warm up"

Treadmill. I feel like it gets my body ready for workouts better than going straight to the exercises.
