Have a blast!!
Try to eat low carb..........
Yeah right............
Dunno what the reason for not training is, but it does give the body a break and injuries a chance to heal. If u did want to train a bit w/out a gym, you could always do isometrics for legs, pushups, triceps off the end of a table, curl anything for arms, sit-ups, etc. At least a bit to make use of all the food you most likely will be eating. You don't have to do cardio, no, but if you do some simple, yet effective exercises, it could be kind of like a mini-unintentional bulk........just something to think about. Have fun!
