@anylene The key is finding something you don't hate!
If working the machines at the gym isn't your thing, try taking a class like body pump, cardio kickbox, Zumba, something else fun.
Try your hand at cycling, or do indoor spin classes. The Peloton app videos are fantastic and you can do them on any spin bike.
What about a team sport? Join a rec league for soccer, rugby, roller derby, something that will keep you moving really hard.
Try your hand at distance running! Find a plan, sign up for a race, push yourself to beat your personal best times.
If your gym has a pool, get some swim lessons (if you don't know how) and do some laps. You can join a local master's swim group to do group workouts, or there are tons of individual plans out there online.
Once you find something you actually enjoy, it's so much better!
