that’s actually about my height and weight too! I would focus on eating 150-180ish grams of protein a day (I know it sounds crazy, but you can get protein from a lot of sources to mix it up and oikos pro protein yogurt is a game changer); for cardio and weights, I would start focusing on HIIT training (with sets of sprints and sets of stairs, I like to start with some sprints after stretching and warming up and then end workout with 20-60 min. of stairs or a few sets of stairs 5-10 minutes each
for arms, I would just try to do a split of shoulders one day, back another, biceps another, forearms another (four day total), and then the next week I do all arm muscles every other day with increased focus on legs in between days; then I switch back to first part of cycle with each day being separate.
