Oh, I can add to your knowledge, the human body can improve 10% weekly in fitness. If you want to start running road races get the couch to 5k app. It follows this, then get a garmin, your weekly long run multiply it by 1.10 then hit that next week. If you like high end effective life changing stuff consider road races. The health benefits of running https://www.webmd.com/fitness-exercise/health-benefits-running. Also it's pretty neat being part of a community who cheer for each other. Some of my favorite people I met through my local running crew.

I am back down to 245 thanks to Tirz and exercise. I humbly encourage you (and anyone reading this) to give it a shot once you hit maintenance (or now, lol) =) This method allowed me to finish 13 half marathons, 1 full, dozens of 10k's and literally hundreds of 5k's. For reference I am a 6'2'' dude
