Doesn't your university have a gym? Take advantage of it. Take a weight lifting class if you can. Look for a trainer if you can't. There's no beating weights, in my opinion. Your stated goal is long-term health. I don't think you can beat the bone density benefits of free weights. Also, in my experience, people who concoct their own fitness schemes tend to ignore bad form and unbalanced routines. There are countless dudes on Internet forums showing off their pectoral gains while ignoring their awful posture. If you refuse to use free weights, then take yoga classes. You'll discover muscles you didn't even know you have, and you'll have your form corrected by the instructor.
