How to resist junk food and go to the gym more often

I personally had avoided the gym my whole life Bc I felt intimidated, and didn’t know how to use the machines. What I found what helped me was:

go with friends, preferably right after class or work. Creates social obligation, and class acts as a trigger to go vs ‘when you want to go’.
no one cares, the same way I don’t notice others at the gym
don’t buy junk food at all. Find healthier alternatives like baby carrots and hummus and fruits. I found by not even having it in the house prevented me from unhealthy snacking.
when you’re craving a snack, ask yourself if youd want to eat an apple. If the answer’s no, it means you’re not actually hungry, but just want something to eat Bc you’re bored etc.
also, if you’re snack-hungry, try a glass of water first. Sometimes our bodies mistake thirst for hunger.
try a different physical activity, join a club. Indoor soccer, b-ball, etc. I found a team sport is a lot more fun, keeps me accountable, and the exercise and increased endurance was a great side benefit
eat meals that are more filling, w beans and other proteins. They keep you fuller longer, and aren’t filled w empty calories.
biking and jogging is also a great way to get exercise, and your brain is naturally occupied vs jogging in place on a treadmill
my personal motivation: don’t let another summer go by with a body that you don’t feel good in, and if you’re single, you never know who you’re gonna meet.
