Jailhouse Gym

A place inside of your extremely tiny apartment where you have purchased very low end or used pieces of gym equiptment/fitness apparatus's. This is due to the country shutting everything down, especially places in which you could actually boost your immune system via exercise (i.e., a gym, a healthclub or a yoga studio) but alas, you are trapped at home"for the health & safety of all". Bit by bit you acquire workout tools and video's, and as time goes on, you learn how to exercise in a 10 foot by 10 foot area-dodging couches, the dog, having your husband leave the room so that you can do some "Just Dance." A jailhouse gym is the poor man's only way to somewhat maintain any kind of workout or exercise routine, & is set up in an extremely small area where movement is barely possible.

Friend: "Hey, what have you been up to during the lockdown?" Me: "Just been trying to not go completely insane by working out in my jailhouse gym."

What is gym hostage

gym casual

A term used to describe a dress code consisting of spandex, shorts, sneakers, sports bras, and similar clothing typically found in a gym, but often worn outside of the gym. Gym casual is more relaxed than black tie, business casual, or casual attire, but more formal than pajamas.

Sarah was thrilled when the invitation called for gym casual attire. No need to spend a dime on new clothes or be uncomfortable. And with her spandex leggings on, she can eat whatever she wants.
