Go for walks, push ups, sit ups, pull ups, unweighted squats, aerobics, swimming, even yoga. There's plenty of exercise to be done without weights, much less a gym. Carve out your 30 minutes a day and do whatever you choose for those 30 minutes. The better shape you are in, the faster / more you can do. I used to love the gym, but the ones around me are severely overbooked, so I don't like them anymore.
