CIRCLE ARROW encompasses whole of your life. movement toward goal. arrow usually means something is targeted, as well as target marks showing places maybe that are targeted on body.
variation where body is slightly amorphous (in process of change?) and not yet at it's goal. Body form shows activity and joy. Lettering in circle emphasizes whole of life. Format would play well both on stationary or t-shirts or whatever.
variation, changing outside line on circle to black, slightly more definition,having a shadow on the inside of the circle gives a sense of journey, entering a space. Some of the others have that same shadow though. Another thing about the slightly amorphous body is that it doesn't say to the overweight that only the perfect enter here, and since this is a fat loss program that would make it less judgemental, elitist, scarey?
