BeFitin90 question

PookDo68

I'm a big guy 44 years old 6 feet around 340 pounds . I am considering doing BeFitin90. It looks very interesting . Is this something I can do or should I start with something else first? My goals in to get down to 195 ibs and get in the best shape of my life. I work a lot and I like how this is around a half hour
