A lot of exercises you can do in the gym you can also do at home with a pair of dumbbells or even just your body weight.

The benefits of the gym for me is having an air conditioned environment, with machines that can guide my exercises and help enforce proper form, a good space to meetup with personal trainers, opportunities for group classes, and somewhere where there’s people around in case anything goes wrong in one of my exercises.

Not all gyms are the same too. There are climbing gyms, kickboxing gyms, mma gyms, gyms with pools, gyms with basketball and volleyball courts, gyms with tennis, squash, and badminton courts, etc. A lot of those you can’t do from home.
