My apartment complex has a half decent gym that I use a few times a week, just the basic standard equipment. I use to go more but most mornings now before work/class I go out and run with my dog (approx. 2.5 miles) instead. When I do go to the gym I usually use the machines and do some benching. If I feel like staying in I'll do pushups/crunches/etc. No real pattern involved, just enough to keep me feeling fit.
