My current lift routine:
Warm up:walking and jogging
Bench press
Recently added back: alternating between lat pull down and seated row both on machines
Calf raises
Core workout: crunches, side crunches, planks, other movements with exercise ball

I do this every other day to every third day. If I don't feel like lifting I'll do cardio consisting of alternating jogging and walking and sprints; rower.
I like the gains and changes so far. I'm wondering if I should add arms. I feel like they get worked out through the other exercises already. Sometimes I'll do chest press on a machine too.

Btw, I used to do more. then I read on the internet that deadlift, bench press, and squats are all you really need for a complete body workout.
