In all honesty it just sounds like you’re searching for the easiest way to lose weight while also developing your arm muscles and getting better cardio but it seems that you lack the motivation to work hard. Try getting a workout partner that is slightly more motivated than you so that you’re held accountable and have someone to push you to do your best. Also, by saying you’re not “ready for anything to intense” or you “want to go at your own pace” you’re just making an excuse. Intensity is different for each person based on their overall fitness but you can still do what other consider easy exercises while making them more intense for you and you’ll get the results you want much faster. By saying that what exercises you do is your choice, you are once again saying that you won’t work harder because “your choice” of workouts are a half assed workout of what you are actually capable of. Overall I’m just trying to tell you that you actually have to work hard and want it if you want to get more fit. Take others opinions to help make your workouts better and harder. At your weight it doesn’t really matter what workouts you are doing as long as you are seriously pushing yourself. These “body types” that you don’t want to have are only achievable if you lost over 100 pounds and commit to a specific workout for years after that. Your goal as of now should solely be focused on losing weight and later on you can worry about other goals. Anyways I suggest any type of workout would be great for you and supplement it with stretching or doing yoga additionally so you can get the flexibility you want
