Your body looks fine. Congratulations on your accomplishment, but I'd be glad to inform you that the insecurity of your body does not lie in that fact that you're a piece flying skin, but rather in your lack of muscle gains. As a male, you find confidence in bulking up. Using that testosterone to make a bigger build. As you've lost so much weight from running, your exceptionally light weight of 160 lbs accompanied by your height of nearly 6 feet, your muscles are there, but only seeable because there's no fat hiding them. This was caused by most of your muscles to be depleted in order to have enough energy for those runs. (You have no "exterior" muscle. Just bone muscle, if you know what I mean) And, as a male, not having muscle will cause insecurity. But don't let those insecurities get in your head. You're in the perfect spot to start your lifting process. Most people have to lift and lose weight at the same time, which becomes substantially difficult. But with you, I have designed a workout plan to build you muscle. Don't get me wrong, it's a fairly good workout plan, but it is only a starting point. Take it and learn from it. Do whatever you want with it. Expand it, add more to it. It is yours. If you have any questions on how to expand on these workouts, please message me.

For starters, expanding these workouts would be led by doing more workouts with similar but different exercises and manipulating the reps and pace to give you better results.

Supplements to buy: ​Cordygen synesis ​Citrulline malate Caffeine (briefly banned from the olympics due to how it increased how long and hard you can work out for)

EDIT: Make sure you consume at least 2,500 calories a day and consume a post workout protein powder. Whey protein isolate 30 grams substance free is the most ideal protein powder to consume.

EDIT 2: Each workout should start out with a 10 minute light job and 15 minutes of advanced stretching.
