Ok, I have a few questions about lifting weights. I have always thought of it to be a necessity to one who wants to be fit, as it makes you stronger, strengthens your bones, makes you look better, etc etc. However lately I've been thinking of some of the bad side effects such as problems with wrists and other such body parts from lifting, and it doesn't really seem to promote a healthy lifestyle (gain, cut, gain, cut). So what I was wondering is what do you people feel is the optimum way to train with weights for one who is purely concerned with strength and endurance, and overall fitness, not so much to get massive and look ripped. I want to be as fit and healthy as possible and lifting heavy weights doesn't seem to promote this. But I could be very wrong. Thoughts?
