If your goal is to build strength, fitness, and physical discipline, but you want to avoid injuries, martial arts is in general a very bad choice. Sports injuries are extremely common even if you are trying your best to avoid them in the majority of martial arts (including grappling arts). Purely maximizing strength and fitness and minimizing injury would look like some form of resistance training combined with low-impact cardio like swimming or cycling. Martial arts with minimal injury would look like a boxing fitness class (as opposed to a boxing class) or something with slow motion sparring or no sparring. Not sexy at all, or particularly helpful in a fight, but safe.
