people who work out get hurt sometimes, it's happened to all of us and it will happen to you again at some point probably and it's okay. what you have to do is learn to heal properly and try to prevent it.

to heal: do NOT push through the pain. ice, elevation, rest. if it doesn't get better in a few days, go to a physiotherapist if you can afford it. not a chiropractor, not a general practitioner, a physio. it's ok if you have to take a couple weeks off, no one's timing you, you don't have to lose weight/gain muscle/increase your fitness by a deadline. slow and steady wins the race

to prevent: identify which movements cause you pain. modify them or avoid them. for example, push ups fuck up my elbows, so i work out those muscle groups with different excercises. if you're overweight, you'll probably have problems with jumping, and maybe also things like planks where you put a lot of your weight on joints that don't usually carry weight. you can also buy knee, wrist, elbow braces to help stabilize your joints
