i am currently working out in my garage. i have a bench,barbell,ez curl bar,dumbells and a pull up bar. i dont know if i should just keep on working in the garage or join a gym. i know that sooner or later im going to outgrow the weights that i have and need to buy more. i also feel that i can get injured easier working out in the garage since theres usually no1 to spot me. what do you guys think?
