16; 5’9 and 170

Hi I’m 16 years old, 5’9 and weigh around 170 pounds (size 13 in pants). Is that a good weight or am I overweight? I used to play volleyball and was around 150.. and now that I stopped I’ve gained 20 pounds😨. I really struggle with my body imagine and I’m not really a “get up and go to the gym” person. So it’ll be great if someone could tell me if my weight was fine // day I am overweight what are some ways to lose the fat
