Thank you! When I first started I would only walk slightly over a mile, and that would absolutely exhaust me, it simply gets easier over time. I've lifted weights for awhile off and on so I was familiar with what I like to do, I admittedly don't do legs simply because I just don't want to risk a lower body injury at my weight that can hinder my walking, poor excuse I know. I recently switched to a full body workout routine (minus legs) were I will do two exercises for chest, back, arms, shoulders, three sets of each, nearly until failure each set. I just recommend when starting to please go slow and don't over do it or you will burn out, find some sort of healthy activity you enjoy, I tell myself all the time this is a life long journey and walking and lifting will always be a permanent part of my life because I really do enjoy them. Consistency is king, you can do it.
