For running, I personally like pace music - a set of songs with the same BPM that I can run to. Or sometimes podcasts, audiobooks, or language lessons. I prefer to run outside when I can and take different routes every day. Smart small and don’t go too big too fast, increase your time no more than 10% per week. Biking is a way to explore the city. Sports like tennis or ultimate frisbee are a way to run while playing games. There are lots of meetup groups for hiking.
Changing eating habits is very hard. I started by tracking what I ate without trying to change it. Just monitoring by writing it down, looking up macros and calories, can help you see your inputs more clearly. If I count calories, it helps me mentally to save room for a treat at the end of the day. Counting calories did help me make better choices too; suddenly carrots and pickles seem like a way to cheat and eat something bulky and filling without blowing my budget, chips and cookies become easier to avoid because of how fast they use up my budget.
