Fitness Goals Support Group
This community is dedicated to group support around achieving fitness goals, whatever they may be, through personal training, athletic activites, or other strenuous activity. Whether you are trying to get fit to treat a health problem, boost your mood, relieve stress, or tone your body, this group is a great place to meet other like-minded people who have similar goals.
While it does require strength, what it won't do is help you build muscle, for that you need weight training. I think you would be wise to consult a professional trainer, if only for a couple of sessions, to come up with a routine that works for you. I think your height and correspondingly longer limbs are somewhat of a factor, what works for a shorter person (I'm nearly a foot shorter than you) might not get you all the results you are looking for.
